The Prince are evaluating a project that costs $900,000, has a 10-year life, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at 160,000 units per year. Price per unit is $32, variable cost per unit is $12, and fixed costs are $650,320 per year. The tax rate is 25 percent, and the company requires a 12 percent return on this project. Suppose the projections given for price, quantity, variable costs, and fixed costs are all accurate to within 15 percent. Calculate:

1. the worst-case NPV
2. the best-case NPV
