16. Mulvey Company derived the following cost relationship from a regression analysis of its monthly manufacturing
overhead cost:
C = P80,000 + P12M
Where C = monthly manufacturing overhead cost
M = machine hours
The standard error of the estimate of the regression is P6,000.
The standard time required to manufacture one six-unit case of Mulvey's angle product is 4 machine hours.
Mulvey applies manufacturing overhead to production on the basis of machine hours and its normal annual
production is 50,000 cases
Mulvey's estimated variable manufacturing overhead cost for a month in which scheduled production is 5,000
cases would be
A. P80,000
C. P240,000
B. P320,000
D. P360,000
50000X 4= 20000

Fixed Costs
9. Parts Company wishes to determine the fixed portion of its maintenance expense (a semi-variable expense), as
measured against direct labor hours for the first three months of the year. The inspection costs are fixed; the
adjustments necessitated by errors found during inspection account for the variable portion of the maintenance
costs. Information for the first quarter is as follows:

Total Costs
17. Molds Corporation has developed the following flexible budget formula for annual indirect labor costs:

6. The following cost functions were developed for manufacturing overhead costs:
Manufacturing Overhead Costs
Cost Function
Electricity
P100 + P20 per direct labor hour
Maintenance
P200 + P30 per direct labor hour
Supervisors’ salaries
P10,000 per month
Indirect materials
P16 per direct labor hour

overhead costs would be
A. P109,300
C. P76,300
B. P99,000
D. P10,366
Electricity = 100 + ( 20*1500) = 100+30000 = 30100
Maintenance = 200+ (30 *1500) = 200+45000= 45200
Supervisor salaries= 10000
Indirect materials = 16*1500= 24000
7. El Noche, Inc. has a total of 2,000 rooms in its nationwide chain of hotels. On the average, 70% of the rooms
are occupied each day. The company’s operating costs are P21 per occupied room per day at this occupancy

November?
A. P1,056,000
C. P846,000
B. P756,000
D. P829,500
