We are evaluating a project that costs $520,000, has a six-year life, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at 73,000 units per year. Price per unit is $45, variable cost per unit is $30, and fixed costs are $840,000 per year. The tax rate is 35 percent, and we require a return of 10 percent on this project. a-1 Calculate the accounting break-even point. (Do not round intermediate calculations. Round your answer to the nearest whole number, e.g., 32.) Break-even point units a-2 What is the degree of operating leverage at the accounting break-even point? (Do not round intermediate calculations. Round your answer to 3 decimal places, e.g., 32.161.) DOL b-1 Calculate the base-case cash flow and NPV. (Do not round intermediate calculations. Round your cash flow answer to the nearest whole number, e.g., 32. Round your NPV answer to 2 decimal places, e.g., 32.16.) Cash flow $ NPV $ b-2 What is the sensitivity of NPV to changes in the sales figure? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) ΔNPV/ΔQ $ c. What is the sensitivity of OCF to changes in the variable cost figure? (Negative amount should be indicated by a minus sign. Do not round intermediate calculations. Round your answer to the nearest whole number, e.g., 32. ) ΔOCF/ΔVC $
