Need help with last two requirements. First two already solved (92,980 as maintenance cost in July and Y= $15,700 + 1.12 X)

Return to questo Problem 5A-8 (Algo) High-Low Method; Predicting Cost [LO5-10] Nova Company's total overhead cost at various levels of activity are presented below: Total Month Machine-tour Overhead cost April 49,000 $ 187,400 May 39,000 $ 165,20 June 59,000 $ 209,680 59,000 $ 21,880 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: July UUSI ities (variable) Supervisory salaries (fixed) Maintenance (mixed) Total overhead coat 42,900 63,000 59.00 165.200 Nova Company's management wants to break down the mointenance cost into its variable and fixed cost elements. Required: 1. Estimate how much of the $231,880 of overhead cost in July was maintenance cost. (Hint to do this, it may be helpful to first determine how much of the $231,880 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 Ya.X 4. What total overhead cost would you expect to be incurred at an activity level of 44,000 machine hours? Required 1 Required 2 Required 3 Required 4 Express the company's total overhead cost in the form Y-a + bx. (Do not round your intermediate calculations.
