We are evaluating a project that costs $713,000, has a life of fourteen years, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at 99,000 units per year. Price per unit is $38, variable cost per unit is $25, and fixed costs are $715,139 per year. The tax rate is 22 percent, and we require a return of 15 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. b. Calculate the worst-case NPV
