We are evaluating a project that costs $740,000, has a life of twelve years, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at 81,000 units per year. Price per unit is $44, variable cost per unit is $28, and fixed costs are $745,920 per year. The tax rate is 25 percent, and we require a return of 20 percent on this project. The projections given for price, quantity, variable costs, and fixed costs are all accurate to within +/- 16 percent. a. Calculate the best-case NPV. b. Calculate the worst-case NPV
