We are evaluating a project that costs $866.000, has a life of thirteen years, and has no salvage value. Assume that depreciation is stralght-line to zero over the life of the project. Sales are projected at 104.000 units per year. Price per unit is $40, varlable cost per unit is $20, and fixed costs are $868.598 per year. The tax rate is 23 percent, and we require a return of 13 percent on this project. The projections given for price, quantity variable costs, and fixed costs are all accurate to within +/-21 percent. a. Calculate the best-case NPV. b. Calculate the worst-case NPV
