We are evaluating a project that costs $832,000, has an eleven-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 84,000 units per year. Price per unit is $39, variable cost per unit is $28, and fixed costs are $848,640 per year. The tax rate is 34 percent, and we require a 17 percent return on this project. The projections given for price, quantity, variable costs, and fixed costs are all accurate to within +/- 13 percent.

Required:

(a) Calculate the best-case NPV.

(b) Calculate the worst-case NPV.
