He estimates that the following costs will be incurred during his first year of operations: Rent $9, 200, Depreciation on equipment $7, 000, Wages $16, 400, Motor oil $2.00 per quart. He estimates that each oil change will require 5 quarts of oil. Oil filters will cost $3.00 each. He must also pay The Fast 'n Clean Corporation a franchise fee of $1.10 per oil change, since he will operate the business as a franchise. In addition, utility costs are expected to behave in relation to the number of oil changes as follows: Number of Oil Changes Utility Costs 4, 000 $ 6, 000 6, 000 $ 7, 300 9, 000 $ 9, 600 12, 000 $ 12, 600 14, 000 $ 15, 000 Bill Braddock anticipates that he can provide the oil change service with a filter at $25 each. Instructions (a) Using the high-low method, determine variable costs per unit and total fixed costs. (b) Determine the break-even point in number of oil changes and sales dollars
