Crosshill Company's total overhead costs at various levels of activity are presented below: Total Overhead Month MachineHou rs Cost April 57, 000 $119, 000 May 47.000 $149,000 June 67, 000 $339, 000 July 78, 000 $177, 000 Assume that the overhead cost above consists of utilities, supervisory salaries, and maintenance. The breakdown of these costs at the 47,000-machine-hour level of activity in May is as follows: Utilities (variable) $ 22.000 Supervisory salaries (fixed) 24,000 Maintenance (mixed) 103,000 Total overhead cost $149,000 The company wants to break down the maintenance cost into its variable and xed cost elements. Required: 1. Estimate how much of the $177,000 of overhead cost in July was maintenance cost. (Hint: To do this, first determine how much of the $177,000 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.) 2. Using the highlow method, estimate a cost formula for maintenance. (Round the "Variable cost per unit" to 2 decimal places.) High activity level Low activity level Variable cost element Fixed cost element 3. Express the company's total overhead cost in the form Y = a + bX. (Round the "Variable cost per unit" to 2 decimal places.) Supervisory salaries cost 4. What total overhead cost would you expect to be incurred at an activity level of 62,000 machine-hours? (Round the "Variable cost per unit" to 2 decimal places.) :|
