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		69,900		93,200
Total factory overhead costs	$	295,100	$	341,700

The factory overhead costs above consist of indirect materials, rent, and maintenance. The company has analyzed these costs at the 69,900-hour level of activity as follows:

Indirect materials (variable)	$	104,850
Rent (fixed)		125,000
Maintenance (mixed)		65,250
Total factory overhead costs	$	295,100

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 $341,700 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 $341,700 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. (Do not round intermediate calculations.)

3.	What total factory overhead costs would you expect the company to incur at an operating level of 76,890 direct labor-hours? (Do not round intermediate calculations.)
