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		54,900		73,200
Total factory overhead costs	$	272,500	$	309,100

The factory overhead costs above consist of indirect materials, rent, and maintenance. The company has analyzed these costs at the 54,900-hour level of activity as follows:

Indirect materials (variable)	$	93,330
Rent (fixed)		136,000
Maintenance (mixed)		43,170
Total factory overhead costs	$	272,500

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 $309,100 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 $309,100 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. Round "Variable cost element" to 2 decimal places.)

3.	What total factory overhead costs would you expect the company to incur at an operating level of 60,390 direct labor-hours?(Do not round intermediate calculations.)
