We are evaluating a project that costs $604,100, 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 $44, variable cost per unit is $31, and fixed costs are $710,000 per year. The tax rate is 23 percent, and we require a return of 12 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-2.	What is the degree of operating leverage at the accounting break-even point? (Do not round intermediate calculations and round your answer to 3 decimal places, e.g., 32.161.)
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.)
b-2.	What is the sensitivity of NPV to changes in the quantity sold? (Do not round 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. )
