We are evaluating a project that costs $728,000, 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 148,000 units per year. Price per unit is $37, variable cost per unit is $26, and fixed costs are $733,096 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 +/- 13 percent.

a. Calculate the best-case NPV.

b. Calculate the worst-case NPV.
