We are evaluating a project that costs $704,000, has a life of eight years, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at 111,000 units per year. Price per unit is $42, variable cost per unit is $21, and fixed costs are $706,816 per year. The tax rate is 24 percent, and we require a return of 18 percent on this project. The projections given for price, quantity, variable costs, and fixed costs are all accurate to within +/19 percent. a. Calculate the best-case NPV. Best case b. Calculate the worst-case NPV
