We are evaluating a project that costs $842,000, has a life of fifteen years, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at 149,000 units per year. Price per unit is $43, variable cost per unit is $22, and fixed costs are $847,894 per year. The tax rate is 24 percent, and we require a return of 14 percent on this project. The projections given for price, quantity, variable costs, and fixed costs are all accurate to within +/- 15 percent a. Calculate the best-case NPV. Best case k 3 nces b. Calculate the worst-case NPV. Worst case
