Sawaya Co., Ltd., of Japan is a manufacturing company whose total factory overhead costs fluctuate considerably from year to year according to increases and decreases in the number of direct labor-hours worked in the factory. Total factory overhead costs at high and low levels of activity for recent years are given below:
Level of Activity | ||||||
Low | High | |||||
Direct labor-hours | 52,800 | 70,400 | ||||
Total factory overhead costs | $ | 286,620 | $ | 328,860 | ||
The factory overhead costs above consist of indirect materials, rent, and maintenance. The company has analyzed these costs at the 52,800-hour level of activity as follows:
Indirect materials (variable) | $ | 95,040 | ||
Rent (fixed) | 125,000 | |||
Maintenance (mixed) | 66,580 | |||
Total factory overhead costs | $ | 286,620 | ||
To have data available for planning, the company wants to break down the maintenance cost into its variable and fixed cost elements.
Required:
1. Estimate how much of the $328,860 factory overhead cost at the high level of activity consists of maintenance cost. (Hint: To do this, it may be helpful to first determine how much of the $328,860 consists of indirect materials and rent. Think about the behavior of variable and fixed costs!) (Do not round intermediate calculations.)
2. Using the high-low method, estimate a cost formula for maintenance. (Round the Variable cost per DLH to 2 decimal places.)

3. What total factory overhead costs would you expect the company to incur at an operating level of 58,080 direct labor-hours? (Do not round intermediate calculations.)
1. Estimate how much of the $328,860 factory overhead cost at the high level of activity consists of maintenance cost :
Indirect materials (variable) | 126720 |
Rent (fixed) | 125000 |
Maintenance (mixed) | 77140 |
Total factory overhead | 328860 |
2) estimate cost formula :
|
Y = 34900+0.60X
3. What total factory overhead costs would you expect the company to incur at an operating level of 58,080 direct labor-hours?
Total factory overhead = (58080*.60+34900) = 69748
