We are evaluating a project that costs $797,000, has a life of eight years, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at 140,000 units per year. Price per unit is $38, variable cost per unit is $26, and fixed costs are $811,346 per year. The tax rate is 22 percent, and we require a return of 16 percent on this project. The projections given for price, quantity, variable costs, and fixed costs are all accurate to within +/- 14 percent.

a. Calculate the best-case NPV.

b. Calculate the worst-case NPV.
