We are evaluating a project that costs $740,000, 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 121,000 units per year. Price per unit is $40, variable cost per unit is $28, and fixed costs are $749,620 per year . The tax rate is 23 percent, and we require a return of 18 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. Best case b. Calculate the worst-case NPV. Worst case
