i just need 1-4 of the required section thank you!

Problem 5A-8 (Algo) High-Low Method; Predicting Cost (L05-10) May Nova Company's total overhead cost at various levels of activity are presented below Total Overhead Month Machine Hours (cast April $4,000 $ 199,500 44,000 $ 173,500 Tune 64,000 $ 225,500 July 74,000 $ 251,500 Assume that the total overhead cost above consists of utilities, supervisory solarles, and maintenance. The breakdown of these costs at the 44,000 machine hour level of activity is utilities (variable) $ 61,600 Supervisory salaries (fixed) 42,000 Maintenance (mixed) 69,900 Total overhead cost 3.173,500 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 $251,500 of overhead cost in July was maintenance cost. (Hint to do this, it may be helpful to first determine how much of the $251,500 consisted of utilities and supervisory salaries. Think about the behavior of varioble and fixed costs.) 2. Using the high low method, estimate a cost formula for maintenance in the form Yox 3. Express the company's total overhead cost in the form Yox 4. What total overhead cost would you expect to be incurred at an activity level of 49,000 machine hours
