Nova Companys total overhead cost at various levels of activity are presented below:

Month	Machine-Hours	Total Overhead Cost
April	49,000	$ 216,110
May	39,000	$ 189,210
June	59,000	$ 243,010
July	69,000	$ 269,910

Assume that the total overhead cost above consists of utilities, supervisory salaries, and maintenance. The breakdown of these costs at the 39,000 machine-hour level of activity is:

Utilities (variable)	$ 62,400
Supervisory salaries (fixed)	70,000
Maintenance (mixed)	56,810
Total overhead cost	$ 189,210

Nova Companys management wants to break down the maintenance cost into its variable and fixed cost elements.

Required:

1. Estimate how much of the $269,910 of overhead cost in July was maintenance cost. (Hint: to do this, it may be helpful to first determine how much of the $269,910 consisted of utilities and supervisory salaries. Think about the behavior of variable and fixed costs.)

2. Using the high-low method, estimate a cost formula for maintenance in the form Y = a + bX.

3. Express the companys total overhead cost in the form Y = a + bX.

4. What total overhead cost would you expect to be incurred at an activity level of 44,000 machine-hours?
