Ans: C AACSB: Analytic AICPA BB: Critical Thinking
AICPA FN: Reporting LO: 1,3,4 Level: Hard
Solution:
Variable component of cost of goods sold:
Variable cost = Change in costs/Change in units
Variable cost = ($502,800 − $419,000)/(6,000 − 5,000)
Variable cost = $83.80 per unit
Variable component of selling and administrative expenses:
Variable cost = Change in costs/Change in units
Variable cost = ($202,200 − $186,500)/(6,000 − 5,000)
Variable cost = $15.70 per unit

Variable cost = Change in cost ÷ Change in activity
= ($4,500 − $3,600) ÷ (18,000 – 9,000) = $0.10
Fixed cost element = Total cost − Variable cost element
= $4,500 − ($0.10 × 18,000) = $2,700
Therefore, the cost formula for total utility cost is $2,700 per period plus $0.10 per
machine-hour, or Y = $2,700 + $0.10X.
At an activity level of 13,000 machine-hours, total cost is estimated to be:
Y = $2,700 + ($0.10 × 13,000) = $4,000

Fixed cost element = Total cost − Variable cost element
= $16,000 − ($0.35 × 32,000) = $4,800
Therefore, the cost formula for total utility cost is $4,800 per period plus $0.35 per
account processed, or Y = $4,800 + $0.35X.
At an activity level of 25,000 accounts, total cost is estimated to be:

Therefore, the cost formula for total shipping cost is $6,000 per period plus $0.75 per
pound shipped, or Y = $6,000 + $0.75X.
At an activity level of 18,000 pounds shipped, total cost is estimated to be:

37. Larson Brothers, Inc., used the high-low method to derive its cost formula for
electrical power cost. According to the cost formula, the variable cost per unit of
activity is $3 per machine-hour. Total electrical power cost at the high level of activity
was $7,600 and at the low level of activity was $7,300. If the high level of activity was
1,200 machine hours, then the low level of activity was:
A) 800 machine hours
B) 900 machine hours
C) 1,000 machine hours
D) 1,100 machine hours
Ans: D AACSB: Analytic AICPA BB: Critical Thinking
AICPA FN: Reporting LO: 1,3 Level: Hard
Solution:
Variable cost = Change in cost ÷ Change in activity
= ($7,600 − $7,300) ÷ (1,200 − X) = $3, where X = low level of activity
=> $300 ÷ (1,200 – X) = $3
=> $300 = $3 × (1,200 – X)
=> $100 = $1,200 – X
=> X = $1,100

Fixed cost element of manufacturing overhead = Total cost − Variable cost element
= $12,400 − ($2.40 × 2,000) = $7,600
Total variable cost per unit = Direct material + Direct labor + Variable manufacturing
overhead = $4.00 + $3.50 + $2.40 = $9.90
There are no fixed direct materials or direct labor, so the total fixed costs would be
equal to the fixed cost portion of manufacturing overhead, or $7,600.

(Alternatively, direct material cost per unit = $364,000 ÷ 5,000 = $72.80)
Direct labor cost per unit = $219,600 ÷ 4,000 = $54.90
(Alternatively, direct labor cost per unit = $274,500 ÷ 5,000 = $54.90)
Variable manufacturing overhead cost = Change in cost ÷ Change in activity
= ($343,000 − $320,400) ÷ (5,000 – 4,000) = $22.60
Total variable manufacturing cost per unit = $72.80 + $54.90 + $22.60 = $150.30

Variable component of cost of goods sold:
Variable cost = Change in costs/Change in units
Variable cost = ($328,500 − $262,800)/(5,000 − 4,000)
Variable cost = $65.70
Fixed cost:
High volume: $328,500 − $65.70 × 5,000 = $0
Low volume: $262,800 − $65.70 × 4,000 = $0
Variable component of selling and administrative expenses:
Variable cost = Change in costs/Change in units
Variable cost = ($244,500 − $230,400)/(5,000 − 4,000)
Variable cost = $14.10 per unit
Fixed cost:
High volume: $244,500 − $14.10 × 5,000 = $174,000
Low volume: $230,400 − $14.10 × 4,000 = $174,000

the following is the cost formula that represents the slope of this line?
A) Y=$4,000+$1.25X
B) Y=$4,000+$0.80X
C) Y=$10,000+$1.33X
D) None of the above is true
Ans: B AACSB: Analytic AICPA BB: Critical Thinking

Solution:
Variable cost = Change in cost ÷ Change in activity
= ($10,000 – $4,000) ÷ (7,500 – 0) = $0.80
Since the regression line passes through the Y axis at the $4,000 point, the $4,000
represents the fixed costs.
Therefore, the cost formula would be Y=$4,000+$0.80X.

Management believes that electrical cost is a mixed cost that depends on machinehours. Using the high-low method to estimate the variable and fixed components of
this cost, these estimates would be closest to:
A) $7.96 per machine-hour; $11,517 per month
B) $11.13 per machine-hour; $40,510 per month
C) $9.61 per machine-hour; $5,533 per month
D) $0.13 per machine-hour; $40,246 per month
Ans: A AACSB: Analytic AICPA BB: Critical Thinking
AICPA FN: Reporting LO: 3 Level: Easy
Solution:
Variable cost = Change in cost ÷ Change in activity
= ($40,706 − $40,268) ÷ (3,667 − 3,612) = $7.96
Fixed cost element = Total cost − Variable cost element
= $40,706 − ($7.96 × 3,667) = $11,517
Therefore, the cost formula for total electrical cost is $11,517 per period plus $7.96
per machine-hour, or Y = $11,517 + $7.96X

of $557,500, and 5,000 units produced with costs of $292,500. Which cost formula
would you estimate using the high-low method?
A) Y=$265,000+$37.17X
B) Y=$160,000+$17.67X
C) Y=$265,000+$58.50X
D) Y=$160,000+$26.50X
Ans: D AACSB: Analytic AICPA BB: Critical Thinking
AICPA FN: Reporting LO: 3 Level: Easy
Solution:
Variable cost = Change in cost ÷ Change in activity
= ($557,500 − $292,500) ÷ (15,000 − 5,000) = $26.50
Fixed cost element = Total cost − Variable cost element
= $557,500 − ($26.50 × 15,000) = $160,000
Therefore, the cost formula for total utility cost is $160,000 per period plus $26.50 per
unit, or Y = $160,000 + $26.50X

To solve this problem, it must be worked backwards. First, calculate what total
variable expenses must be by subtracting the contribution margin from sales
($250,000 − $100,000 = $150,000). Of the total variable expenses, $110,000 is given
in the problem as the variable cost of goods sold, so we would have:
Variable selling and administrative expenses = $150,000 − $110,000 = $40,000.

Solving backwards, gross margin is $20,000 + $55,000 = $75,000.
Since the information given in the problem states that the gross margin exceeds the
contribution margin by $25,000, the contribution margin must be $75,000 − $25,000 =
$50,000.

Solution:
Variable component of sales commissions:
Variable cost = Change in costs/Change in units
Variable cost = ($13,200 − $12,000)/(11,000 − 10,000)
Variable cost = $1.20
Fixed cost of sales commissions:
High volume: $13,200 − $1.20 × 11,000 = $0 (answer will be zero fixed costs,
because these sales commissions are variable, not mixed)
Low volume: $12,000 − $1.20 × 10,000 = $0
Variable component of maintenance expenses:
Variable cost = Change in costs/Change in units
Variable cost = ($13,500 − $13,000)/(11,000 − 10,000)
Variable cost = $0.50
Fixed cost of maintenance expenses:
High volume: $13,500 − $0.50 × 11,000 = $8,000
Low volume: $13,000 − $0.50 × 10,000 = $8,000
Variable component of clerical expense:
Variable cost = Change in costs/Change in units
Variable cost = ($16,000 − $15,000)/(11,000 − 10,000)
Variable cost = $1.00
Fixed cost of clerical expense:
High volume: $16,000 − $1.00 × 11,000 = $5,000
Low volume: $15,000 − $1.00 × 10,000 = $5,000
Total variable cost per unit:
$1.20 + $0.50 + $1.00 = $2.70
Total fixed cost:
$0 + $8,000 + $5,000 + $12,000* = $25,000

Chapter 5 Cost Behavior: Analysis and Use
Ans:
a. Variable component of cost of goods sold:
Variable cost = Change in costs/Change in units
Variable cost = ($710,000 − $550,000)/(70,000 − 50,000)
Variable cost = $8.00
Fixed cost:
High volume: $710,000 − $8.00×70,000 = $150,000
Low volume: $550,000 − $8.00×50,000 = $150,000
Variable component of selling and administrative expenses:
Variable cost = Change in costs/Change in units
Variable cost = ($190,000 − $150,000)/(70,000 − 50,000)
Variable cost = $2.00
Fixed cost:
High volume: $190,000 − $2.00×70,000 = $50,000
Low volume: $150,000 − $2.00×50,000 = $50,000
Total variable cost per unit:
$8.00 + $2.00 = $10.00
Total fixed cost:
$150,000 + $50,000 = $200,000
