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 Activi High 99,600 Low Direct labor-hours Total factory overhead cost:s 74,700 $ 306,830 $ 354,140 The factory overhead costs above consist of indirect materials, rent, and maintenance. The company has analyzed these costs at the 74,700-hour level of activity as follows Indirect materials (variable) Rent (fixed) Maintenance (mixed) Total factory overhead cost:s 112,050 136,000 58,780 $306,830 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 $354,140 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 $354,140 consists of indirect materials and rent. Think about the behavior of variable and fixed costs!) (Do not round intermediate calculations.) Maintenance cost at high level of activity 2. Using the high-low method, estimate a cost formula for maintenance. (Round the Variable cost per DLH to 2 decimal places.) Direct Labor Maintenance Hours Cost High level of activity Low level of activity Change Variable cost element per DLH Fixed cost element 3. What total factory overhead costs would you expect the company to incur at an operating level of 82,170 direct labor-hours? (Do not round intermediate calculations.)
