Nova Company's totat overhead costs at varous levels of acivity follow: Assume that the total overhead costs consist of utilites, supervisory salaties, and maintenance. The breakdown of these costs at the 68.000 machine hour level of activity is as follows: V = variable: F = foxed: M = mixed. Nova Company's management wants to break the maintenance cost down into its basic variable and fixed cost elements: Required: 1. As shown overhead costs in May amounted to $278 , 000 . Determine how much of this consisted of maintenance cost, (hinst To do this, it may be heipful to first determine how much of the $278.000 consisted of utilities and supervisory salanies. Think abeut the behaviour of varlable and fixed costs?) (Do not round intermediote calculotions. Round your answers to the nearest whole dollar omount.) 2. By means of the high- fow method, estimate a cost formula for maintenance. (Do not round intermediate calculntions. found "Fixed cost" nnswer to the nearest whole dollar and "Variable cost" answer to 2 decimal places.) 3. Express the company's total overhead costs in the linear equation form Y = a + b X . (Do not round intermectiate calculatiani. Pound "Fixed cost" answer to the nearest whole dollar and "Variable cost" answer to 2 decimal places.) 4. What total overhead costs would you expect to be incurred at an operating activity level of 68,000 machine hours? At an operating activily level of 83,000 machine-hours? (Do not round intermediate colculations, Round your answers to the nearest whole dollar amount.) 3. Express the company's total overhead costs in the linear equation form Y = a + b X . (Do not round intermediote calculations. Roun "Fixed cost" answer to the nearest whole dollar and "Variable cost" answer to 2 decimal places.) 4. What total overhead costs would you expect to be incurred at an operating activity level of 68,000 machine hours? At an operating activity level of 83,000 machine-hours?
