We are evaluating a project that costs $788,000, 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 91,000 units per year. Price per unit is $42, variable cost per unit is $24, and fixed costs are $793,516 per year. The tax rate is 24 percent, and we require a return of 20 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.
