Crosshill Company's total overhead costs at various levels of activity are presented below: Month April May June July Machine- Hours 51,000 41,000 61,000 71,000 Total Overhead Cost $208,270 $181,570 $234,970 $261,670 Assume that the overhead cost above consists of utilities, supervisory salaries, and maintenance. The breakdown of these costs at the 41,000-machine-hour level of activity in May is as follows: $ Utilities (variable) Supervisory salaries (fixed) Maintenance (mixed) 61,500 56,000 64,070 Total overhead cost S 181,570 The company wants to break down the maintenance cost into its variable and fixed cost elements. Required: 1. Estimate how much of the $261,670 of overhead cost in July was maintenance cost. (Hint: To do this, first determine how much of the $261,670 consisted of utilities and supervisory salaries. Think about the behaviour of variable and fixed costs within the relevant range.) (Do not round intermediate calculations.) Maintenance cost in July $ 99,170 Crosshill Company's total overhead costs at various levels of activity are presented below: Month April May June July Machine- Hours 51,000 41,000 61,000 71,000 Total Overhead Cost $208,270 $181,570 $234,970 $261,670 Assume that the overhead cost above consists of utilities, supervisory salaries, and maintenance.

(Do not round intermediate calculations.) Maintenance cost in July $ 99,170 2. Using the high-low method, estimate a cost formula for maintenance. (Do not round your intermediate calculations. Round the "Variable cost per unit" to 2 decimal places.) Machine- Hours Maintenance Cost High activity level Low activity level Change per MH Variable cost element Fixed cost element Y= + X 3. Express the company's total overhead cost in the form Y = a +bX. (Do not round your intermediate calculations. Round the "Variable cost per unit" to 2 decimal places.) Variable Cost per Machine-Hour Fixed Cost Utilities cost Supervisory salaries cost Maintenance cost Total overhead cost Y = 1 4. What total overhead cost would you expect to be incurred at an activity level of 46,000 machine-hours? (Do not round intermediate calculations.) Total overhead cost
