The breakdown of these costs at the 79,000 machinehour level of activity is as follows: Utilities {v3 5 43,353 Supervisory salaries (F) 22,300 Haintenance (H) 144,840 Total overhead costs $216,000 V = variable; F = fixed: M = mixed. Nova Company's management wants to break the maintenance cost down into its basic variable and xed cost elements. Required: 1. As shown, overhead costs in May amounted to $288,000. Determine how much of this consisted of maintenance cost. (Hint: To do this, it may be helpful to rst determine how much of the $288,000 consisted of utilities and supervisory salaries. Think about the behaviour of variable and fixed costs!) [Do not round intermediate calculations.
