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		58,500		78,000
Total factory overhead costs	$	291,850	$	332,800

The factory overhead costs above consist of indirect materials, rent, and maintenance. The company has analyzed these costs at the 58,500-hour level of activity as follows:

Indirect materials (variable)	$	105,300
Rent (fixed)		134,000
Maintenance (mixed)		52,550
Total factory overhead costs	$	291,850

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 $332,800 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 $332,800 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. (Do not round intermediate calculations.)

	Direct Labor-Hours	Maintenance Cost
High level of activity	78,000
Low level of activity	58,500
Change	19,500	$0
Variable cost element		per DLH
Fixed cost element
