The breakdown of these costs at the 42,000-machine-hour level of activity in May is as follows: $ Utilities (variable) Supervisory salaries (fixed) Maintenance (mixed) 58.800 66,000 62,920 Total overhead cost $ 187,720 The company wants to break down the maintenance cost into its variable and fixed cost elements Required: 1. Estimate how much of the S264,520 of overhead cost in July was maintenance cost (Hot To do this first determine how much of the $264,520 consisted of utilities and supervisory salaries. Think about the behaviour of vonable and fixed costs within the relevant range.) (Do not round intermediate calculation. Maintenance cost in July 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.)
