Prince Companys total overhead costs at various levels of activity are presented below:

Month	Machine Hours	Total Overhead Cost
September		113,000		$	750,650
October		85,000		$	612,050
November		156,000		$	963,500
December		162,600		$	996,170

Assume that the overhead cost above consists of utilities, supervisory salaries, depreciation, and maintenance. The breakdown of these costs at the 85,000-machine-hour level of activity in October is as follows:

Utilities (variable)	$	221,000
Supervisory salaries and depreciation (fixed)		149,000
Maintenance (mixed)		242,050
Total overhead cost	$	612,050

The company wants to break down the maintenance cost into its variable and fixed cost elements.

Required:

1.	Estimate how much of the $996,170 of overhead cost in December was maintenance cost. (Hint:To do this, first determine how much of the $996,170 consisted of utilities and supervisory salaries. Think about the behaviour of variable and fixed costs within the relevant range.)(Do not round intermediate calculations.)

2.	Using the highlow method, estimate a cost formula for maintenance.(Round variable cost to 2 decimal places and fixed cost to the nearest dollar amount.)

3.	Express the companys total overhead cost in the formY=a+bX.(Round variable cost to 2 decimal places and fixed cost to the nearest dollar amount.)

4.	What total overhead cost would you expect to be incurred at an activity level of 95,000 machine-hours?(Do not round intermediate calculations.)
