Nova Company's total overhead cost at various levels of activity are presented below: Assume that the total overhead cost above consists of utilities, supervisory salaries, and maintenance. The breakdown of these cos at the 42,000 machine-hour level of activity is Nova Company's management wants to break down the maintenance cost into its variable and fixed cost elements. Required: 1. Estimate how much of the $238,880 of overhead cost in July was maintenance cost (Hint to do this, it may be helpful to first. determine how much of the $238,880 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 company's 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 47,000 machine-hours?
