Part A What is the accountant's estimate of total "overhead" next month if she uses the cost function based on her analysis of last month's cost data? Part B What is the accountant's estimate of total "overhead" next month if she uses the cost function based on the high-low method?

Charlene is the owner of Charlene's Computer Care (3C) and has been in the business of servicing computers and computer systems at affordable prices for just over five years. 3Cs primary clients are local businesses but include some residential customers. Their advertised approach is to analyze the problem, develop a range of IT options, explain their specific recommendation to the customer, and finally estimate the time and costs associated with the service prior to commencing work. Their approach has proven successful, but competition is getting much stiffer, and Charlene is concerned that her approach to determining costs and prices for any particular job is not correctly incorporating all of the company's costs. She has heard about the concept of cost allocation and asks her accountant to create an allocation system for the business. Her accountant decides to implement a single-driver allocation system and needs to develop a reliable cost function to estimate total indirect costs. She will use this estimate for the numerator of the single driver "overhead" rate, and she will use service hours as the cost driver and denominator in the "overhead" rate. To estimate the parameters of this cost function, the accountant first studied the behavior of last month's costs, when the company spent 286 service hours repairing 37 computer systems. Here are the results of her analysis: Charlene is the owner of Charlene's Computer Care (3C) and has been in the business of servicing computers and computer systems at affordable prices for just over five years. 3Cs primary clients are local businesses but include some residential customers.
