Hello I am having a little problem calculating this problem, can some further assist me? Heres the problem?

PROBLEM 2-20 High-Low Method; Predicting Cost [LO 2-4, LO 2-5]Nova Company's total overhead cost at various levels of activity are presented below:MonthMachine-HoursTotal Overhead CostApril..............70,000$198,000May..............60,000$174,000June .............80,000$222,000July ..............90,000$246,000Assume that the total overhead cost above consists of utilities, supervisory salaries, and main-tenance. The breakdown of these costs at the 60,000 machine-hour level of activity is:Utilities(variable) .......................$ 48,000Supervisorysalaries(fixed)...............21,000Maintenance(mixed) .................... 105,000Totaloverheadcost .....................$174,000Nova Company's management wants to break down the maintenance cost into its variable and fixed cost elements.Required: 1. Estimate how much of the $246,000 of overhead cost in July was maintenance cost. (Hint, it may be helpful to first determine how much of the $246,000 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. 3. Express the company's total overhead cost in the linear equation form Y = a + bX. 4. What total overhead cost would you expect to be incurred at an activity level of 75,000 machine-hours?

Fringe benefits, assembly-line workers. 18. Yarn used in sweater production. 19. Wages of receptionist, executive offices.Required: display headings as shown below. For each cost item, indicate whether it would be variable or fixed with respect to the number of units produced and sold; and then whether it would be a selling cost, an administrative cost, or a manufacturing cost. If it is a manufacturing cost, indicate whether it would typically be treated as a direct cost or an indirect cost with respect to units of product. Three sample answers are provided for illustration.Manufacturing (Product) Cost Direct IndirectCost ItemVariable or FixedSelling CostAdministrative CostDirectlabor .................VXExecutivesalaries............FXFactoryrent.................FXPROBLEM 2-22 High-Low and Scattergraph Analysis [LO 2-4, LO 2-5]Pleasant View Hospital of British Columbia has just hired a new chief administrator who is anx-ious to employ sound management and planning techniques in the business affairs of the hospital. Accordingly, she has directed her assistant to summarize the cost structure of the various depart-ments so that data will be available for planning purposes.The assistant is unsure how to classify the utilities costs in the Radiology Department because these costs do not exhibit either strictly variable or fixed cost behavior. Utilities costs are very high in the department due to a CAT scanner that draws a large amount of power and is kept running at all times. The scanner can't be turned off due to the long warm-up period required for its use. When the scanner is used to scan a patient, it consumes an additional burst of power. The assistant has accumulated the following data on utilities costs and use of the scanner since the first of the year.MonthNumber of ScansUtilities CostJanuary.....................60$2,200February....................70$2,600March ......................90$2,900April........................120$3,300May........................100$3,000June .......................130$3,600July ........................150$4,000August .....................140$3,600September..................110$3,100October ....................80$2,500Final PDF to printer
