Crosshill Company's total overhead costs at various levels of activity are presented below: Month April May June July Machine Hours 59,000 49,000 69,899 77,000 Total Overhead Cost $205,000 $161,000 $266,000 $222,000 Assume that the overhead cost above consists of utilities, supervisory salaries, and maintenance. The breakdown of these costs at the 49,000-machine hour level of activity in May is as follows: Utilities (variable) Supervisory salaries (Fixed) Maintenance (mixed) Total overhead cost $ 44,000 17,000 100,000 $161,000 The company wants to break down the maintenance cost into its variable and fixed cost elements. Required: 1. Estimate how much of the $222.000 of overhead cost in July was maintenance cost. (Hint To do this first determine how much of the $222,000 consisted of utilities and supervisory salaries. Think about the behaviour of variable and fixed costs within the relevant range.) (Round the "Variable cost per unit" to 2 decimal places.) Required: 1. Estimate how much of the $222,000 of overhead cost in July was maintenance cost.
