We are evaluating a project that costs $883,000, 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 87,000 units per year. Price per unit is $45, variable cost per unit is $29, and fixed costs are $893,596 per year. The tax rate is 21 percent, and we require a return of 17 percent on this project. The projections given for price, quantity, variable costs, and fixed costs are all accurate to within +//-18 percent. a. Calculate the best-case NPV. Best case b. Calculate the worst-case NPV. Worst case
