Problem 11-5 Sensitivity Analysis and Break-Even (LO1, 3] We are evaluating a project that costs $618,100, has a seven-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 90,000 units per year. Price per unit is $45, variable cost per unit is $32, and fixed costs are $715,000 per year. The tax rate is 24 percent, and we require a return of 9 percent on this project. a-1. Calculate the accounting break-even point. (Do not round intermediate calculations and round your answer to the nearest whole number, e.g., 32.) a- What is the degree of operating leverage at the accounting break-even point? (Do 2. not round intermediate calculations and round your answer to 3 decimal places, e.g., 32.161.) b- Calculate the base-case cash flow and NPV. (Do not round intermediate 1. 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.) b- What is the sensitivity of NPV to changes in the quantity sold? (Do not round 2. intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) c. What is the sensitivity of OCF to changes in the variable cost figure? (A negative answer should be indicated by a minus sign. Do not round intermediate calculations and round your answer to the nearest whole number, e.g., 32.) 61,792 units a-1. Break-even point a-2.
