Nova Company's total overhead cost at various levels of activity are presented below: Month April May Machine Hours 49,000 39.000 59,000 69,000 Overhead Cost $ 192,590 $ 166,490 $ 218,690 $ 244,790 July Assume that the total overhead cost above consists of utilities, supervisory salaries, and maintenance. The breakdown of these costs at the 39,000 machine-hour level of activity is Utilities (variable) Supervisory Boare (Eixed) Maintenance (mixed) Total overhead cost 5 56.600 2.000 62,990 5166,490 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 $244.790 of overhead cost in July was maintenance cost (Hint to do this, it may be helpful to first determine how much of the $244790 consisted of utilities and supervisory salaries. Think about the behavior of variable and fixed costs) in the form Yax July 69.000 3244,790 Assume that the total overhead cost above consists of utilities, supervisory salaries, and maintenance. The breakdown of these costs at the 39,000 machine-hour level of activity is: Utilities (variable) Supervisory salaries (fixed) Maintenance (mixed) Total overhead cout $ 54,600 49,000 62,890 $166,90 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 $244,790 of overhead cost in July was maintenance cost. (Hint: to do this, it may be helpful to first determine how much the $244790 consisted of utilities and supervisory salaries. Think about the behavior of variable and fixed costs) 2. Using the high-low method, estimate a cost formula for maintenance in the form Ya+bX 3. Express the company's total overhead cost in the form Y = a +bX 4. What total overhead cost would you expect to be incurred at an activity level of 44.000 machine-hours? 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 Fixed Cost Hour Utilities cost Supervisory salaries cost $ 49,000 Maintenance cost Total overhead cost $ 0.00 $ 49,000 Y the $244,790 consisted of utilities and supervisory salaries.
