The breakdown of these costs at the 38,000 machine-hour level of activity is: Utilities (variable) $ 60,800 Supervisory salaries (fixed) 55.000 Maintenance (mixed) 52,340 Total overhead cost $ 173, 140 Nova Company's management wants to break down the maintenance cost into its variable and fixed cost elements Required: 1. Estimate how much of the $256,540 of overhead cost in July was maintenance cost. (Hintto do this, it may be helpful to first determine how much of the $256,540 consisted of utilities and supervisory salories. Think about the behavior of variable and fixed costs) 2. Using the high-low method, estimate a cost formula for maintenance in the form Y = a + bx 3. Express the company's total overhead cost in the form Y = a +bX 4.
