3. Bill Braddock is considering opening a Fast in Clean Car Service Center. 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 oll 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. Variable Cost Per Unit (Utility) = ($15,000-$6,000/($14,000 - $4,000) = $0.9 per unit Total Variable Cost = (5 x 2) (Oil) + 3(Filter) + 1.10 (Franchise Fee) + 90 (Utility Cost) = $15 per Unit Fixed Cost(Utility) = $15,000 - $14,000*0.9 = $2,400 Total Fixed Cost = $9,200(Rent) + $7,000 (Depreciation) + $16,400 (Wages) + $2,400 (Utility) = $35,000 (b) Determine the break-even point in number of all changes and sales dollars. Break Even Point in Unit = Fixed Cost/(Contribution Per- Unit) = $35,000/(25-15) = 3,500 Oil Changes. Break Even Point in Dollar = 3,500 $25 = $87,500 (C) Without regard to your answers in parts (a) and (b), determine the oll changes required to earn net income of $20,000, assuming fixed costs are $32,000 and the contribution margin per unit is $8. Total Oil Changes Required = (Fixed Cost + Desired Income) / Contribution = ($32,000 - $20,000) / 8 = 6,500 Oil Change +
