2. Using the high-low method, estimate a cost formula for maintenance. (Round the "Variable cost per unit" to 2 decimal places.) 3. Express the company's total overhead cost in the form Y=a+bX. (Round the "Variable cost per unit" to 2 decimal places.) Crosshill Company's total overhead costs at various levels of activity are presented below: Assume that the overhead cost above consists of utilities, supervisory salaries, and maintenance. The breakdown of these costs at the 60,000-machine-hour level of activity in May is as follows: The company wants to break down the maintenance cost into its variable and fixed cost elements. Required: 1. Estimate how much of the $246,000 of overhead cost in July was maintenance cost. (Hint: To do this, first determine how much of the $246,000 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.)
