27. Milford Corporation has in stock 16,100 kilograms of material R that it bought five
years ago for $5.75 per kilogram. This raw material was purchased to use in a product
line that has been discontinued. Material R can be sold as is for scrap for $3.91 per
kilogram. An alternative would be to use material R in one of the company's current
products, S88Y, which currently requires 2 kilograms of a raw material that is
available for $7.60 per kilogram. Material R can be modified at a cost of $0.77 per
kilogram so that it can be used as a substitute for this material in the production of
product S88Y. However, after modification, 4 kilograms of material R is required for
every unit of product S88Y that is produced. Milford Corporation has now received a
request from a company that could use material R in its production process. Assuming
that Milford Corporation could use all of its stock of material R to make product S88Y
or the company could sell all of its stock of the material at the current scrap price of
$3.91 per kilogram, what is the minimum acceptable selling price of material R to the
company that could use material R in its own production process?

Chapter 13 Relevant Costs for Decision Making
Solution:
Product S88Y:
Current cost (2 kg @ $7.60): $15.20
If material R were used, 4 kilograms would be needed. It currently costs $15.20 for
Product S88Y; to maintain this same cost, material R would need to cost $3.03 per
kilogram [($15.20 ÷ 4 kg) − $0.77]. The company should sell material R for $3.91 per
kilogram.
28. Otool Inc. is considering using stocks of an old raw material in a special project. The
special project would require all 240 kilograms of the raw material that are in stock
and that originally cost the company $2,112 in total. If the company were to buy new
supplies of this raw material on the open market, it would cost $9.25 per kilogram.
However, the company has no other use for this raw material and would sell it at the
discounted price of $8.35 per kilogram if it were not used in the special project. The
sale of the raw material would involve delivery to the purchaser at a total cost of
$71.00 for all 240 kilograms. What is the relevant cost of the 240 kilograms of the raw
material when deciding whether to proceed with the special project?
A) $1,933

In the company's accounting system all fixed expenses of the company are fully
allocated to products. Further investigation has revealed that $186,000 of the fixed
manufacturing expenses and $106,000 of the fixed selling and administrative expenses
are avoidable if product L07E is discontinued. What would be the effect on the
company's overall net operating income if product L07E were dropped?
A) Overall net operating income would increase by $8,000.
B) Overall net operating income would decrease by $173,000.

47. Sardi Inc. is considering whether to continue to make a component or to buy it from an

Assume that direct labor is a variable cost. Of the fixed manufacturing overhead, 70%
is avoidable if the component were bought from the outside supplier. In addition,
making the component uses 2 minutes on the machine that is the company's current
constraint. If the component were bought, this machine time would be freed up for use
on another product that requires 4 minutes on the constraining machine and that has a
contribution margin of $7.00 per unit.
When deciding whether to make or buy the component, what cost of making the
component should be compared to the price of buying the component?

The total cost of the make alternative is lower by $163,200 ($353,600 − $190,400).
Thus, net operating income would decline by $163,200 if the offer from the supplier
were accepted. Therefore, the company should continue to make the part itself.

51. Part U16 is used by Mcvean Corporation to make one of its products. A total of 13,000
units of this part are produced and used every year. The company's Accounting
Department reports the following costs of producing the part at this level of activity:
Direct materials..........................................
Direct labor................................................
Variable manufacturing overhead..............
Supervisor’s salary.....................................
Depreciation of special equipment.............
Allocated general overhead........................
Per Unit
$2.90
$7.50
$8.00
$3.40
$1.80
$7.00
An outside supplier has offered to make the part and sell it to the company for $29.80
each. If this offer is accepted, the supervisor's salary and all of the variable costs,
including the direct labor, can be avoided. The special equipment used to make the
part was purchased many years ago and has no salvage value or other use. The
allocated general overhead represents fixed costs of the entire company, none of which
would be avoided if the part were purchased instead of produced internally. In
addition, the space used to make part U16 could be used to make more of one of the
company's other products, generating an additional segment margin of $25,000 per
year for that product. What would be the impact on the company's overall net
operating income of buying part U16 from the outside supplier?
A) Net operating income would increase by $25,000 per year.
B) Net operating income would decline by $79,000 per year.
C) Net operating income would decline by $35,400 per year.
D) Net operating income would increase by $14,600 per year.

Solution:
Total variable expenses................. $120,000
Divided by 15,000 units............... ÷ 15,000
Variable expense per unit..............
$8
Total contribution margin = Fixed expenses plus increase in contribution margin from
other toys
Total contribution margin = 15,000 × (Selling price − Variable expense per unit)
15,000 × (Selling price − $8) = $8,000 + $16,000
15,000 × Selling price − $120,000 = $24,000
15,000 × Selling price = $144,000

Use the following to answer questions 86-87:
Elly Industries is a multi-product company that currently manufactures 30,000 units of Part
MR24 each month for use in production. The facilities now being used to produce Part MR24
have a fixed monthly cost of $150,000 and a capacity to produce 35,000 units per month. If
Elly were to buy part MR24 from an outside supplier, the facilities would be idle, but its fixed
costs would continue at 40% of their present amount. The variable production costs of Part
MR24 are $11 per unit.

Chapter 13 Relevant Costs for Decision Making
Solution:
A company will be indifferent between purchasing and making a part when the outside
purchase price is equal to the total relevant cost per unit of making the part. The total
relevant cost per unit of making the part is composed of the variable production cost
per unit ($11) plus the fixed cost per unit. Since the total cost must be equal to $15,
then the fixed cost per unit must be $4 ($15 − $11).
The fixed cost per unit is calculated as:
Fixed cost per unit = Total relevant fixed costs ÷ Units to be produced
Substituting:
$4 = $90,000 ÷ Units to be produced
Units to be produced = 22,500
Use the following to answer questions 88-90:
Ahron Company makes 80,000 units per year of a part it uses in the products it manufactures.
The unit product cost of this part is computed as follows:
Direct materials..........................................
Direct labor................................................
Variable manufacturing overhead..............
Fixed manufacturing overhead..................
Unit product cost........................................
$14.90
17.50
1.90
21.10
$55.40
An outside supplier has offered to sell the company all of these parts it needs for $46.60 a
unit. If the company accepts this offer, the facilities now being used to make the part could be
used to make more units of a product that is in high demand. The additional contribution
margin on this other product would be $560,000 per year.
If the part were purchased from the outside supplier, all of the direct labor cost of the part
would be avoided. However, $13.60 of the fixed manufacturing overhead cost being applied
to the part would continue even if the part were purchased from the outside supplier. This
fixed manufacturing overhead cost would be applied to the company's remaining products.

The company should be willing to pay up to $13.10 per minute to obtain more of the
constrained resource because this is the value to the company of using this constrained
resource to make more of product VD. By assumption, the other products will already
have been produced up to demand.
Use the following to answer questions 117-118:
The Anthony Company makes two products, X and Y, in a joint process. At the split-off point,
60,000 units of product X and 70,000 units of product Y are available each month. Monthly
joint production costs total $200,000. Product X can be sold at the split-off point for $3.20 per
unit. Product Y can be either sold at the split-off point for $2.60 per unit or it can be processed
further and sold for $5.80 per unit. If product Y is processed further, additional processing
costs of $2.30 per unit will be incurred.

for Anthony to be economically indifferent between selling Y at split-off or processing
Y further before sale?
A) $3.80
B) $3.50
C) $3.20
D) $2.90
Ans: B AACSB: Analytic AICPA BB: Critical Thinking
AICPA FN: Decision Making; Reporting LO: 6 Level: Medium
Solution:
For Anthony to be economically indifferent between selling Y at the split-off or
processing Y further, the incremental revenue from further processing would need to
be equal to the cost of further processing, or:
$5.80 − Sales value at split-off point = $2.30
Sales value at split-off point = $3.50

that if Store B is closed, one-fourth of its traceable fixed expenses will continue
unchanged. The studies also show that closing Store B would result in a 10 percent
decrease in sales in Store A. The company allocates common fixed expenses to the

131. Companies often allocate common fixed costs among segments. For example,
common fixed corporate costs are often allocated to divisions and appear as part of the
divisional performance reports.
Required:
What dangers are there in allocating common fixed costs to segments when involved
in a decision to possibly drop a segment such as a product or a division?
Ans:
A segment such as a product or a division may show a net loss only because of the
allocated common fixed cost. However, if the segment is dropped, the common fixed
expense will continue. A segment should be dropped only if its contribution margin
does not cover its own avoidable fixed costs. And even in cases where a segment does
not cover its own costs, it may be beneficial to retain the segment if it has positive
effects on other segments. For example, a “losing” product may be important in luring
customers into a store where they will buy other products.

Variable manufacturing overhead........
Fixed manufacturing overhead............
Unit product cost..................................
$13.80
18.10
4.30
24.60
$60.80
An outside supplier has offered to sell the company all of these parts it needs for
$51.80 a unit. If the company accepts this offer, the facilities now being used to make
the part could be used to make more units of a product that is in high demand. The
additional contribution margin on this other product would be $268,000 per year.
If the part were purchased from the outside supplier, all of the direct labor cost of the
part would be avoided. However, $17.00 of the fixed manufacturing overhead cost
being applied to the part would continue even if the part were purchased from the
outside supplier. This fixed manufacturing overhead cost would be applied to the
company's remaining products.
Required:
a. How much of the unit product cost of $60.80 is relevant in the decision of whether
to make or buy the part?
b. What is the net total dollar advantage (disadvantage) of purchasing the part rather
than making it?
c. What is the maximum amount the company should be willing to pay an outside
supplier per unit for the part if the supplier commits to supplying all 40,000 units
required each year?

Variable manufacturing overhead........
Fixed manufacturing overhead............
Direct labor-hours................................
$225,000
$630,000

An outside supplier has offered to supply component P0 for $78 each. The outside
supplier is known for quality and reliability. Assume that direct labor is a variable cost,
variable manufacturing overhead is really driven by direct labor-hours, and total fixed
manufacturing overhead would not be affected by this decision. Gottshall chronically
has idle capacity.

Chapter 13 Relevant Costs for Decision Making
Ans:
Direct materials, direct labor, and variable manufacturing overhead are relevant in this
decision. Fixed manufacturing overhead is not relevant since it would not be affected
by the decision. The variable portion of the manufacturing overhead rate is computed
as follows:
Variable portion of the predetermined overhead rate = Variable manufacturing
overhead ÷ Direct labor-hours = $225,000 ÷ 45,000 DLHs = $5.00 per DLH
The direct-labor hours per unit for the special order can be determined as follows:
Direct labor-hours = Manufacturing overhead applied ÷ Predetermined overhead rate
= $32.30 ÷ $19.00 per DLH = 1.70 DLHs
Consequently, the variable manufacturing overhead for the special order would be:
Variable manufacturing overhead = Variable portion of the predetermined overhead
rate × Direct labor-hours = $5.00 per DLH × 1.70 DLHs = $8.50
Putting this all together:
Direct materials..........................................
Direct labor................................................
Variable manufacturing overhead..............
Total variable cost......................................
$21.00
40.80
8.50
$70.30
Since the outside supplier has offered to sell the component for $78.00 each, but it
only costs the company $70.30 to make the component internally, this is not a
financially attractive offer.

Fixed costs are applied to the products on the basis of direct labor hours.
Demand for the three products exceeds the company's productive capacity. The
milling machine is the constraint, with only 2,400 minutes of milling machine time
available this week.
Required:
a. Given the milling machine constraint, which product should be emphasized?
Support your answer with appropriate calculations.
b. Assuming that there is still unfilled demand for the product that the company
should emphasize in part (a) above, up to how much should the company be
willing to pay for an additional hour of milling machine time?
Ans:
a. The product to emphasize can be determined by computing the contribution
margin per unit of the scarce resource, which in this case is milling machine time.

Product G should be emphasized because it has the greatest contribution margin
per unit of the scarce resource.
b. If additional milling machine time would be used to produce more of Product G,
the time would be worth 60 minutes per hour × $15 per minute = $900 per hour.
