We are evaluating a project that costs $750,000, has an twelve-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 109,000 units per year. Price per unit is $42, variable cost per unit is $21, and fixed costs are $750,750 per year. The tax rate is 35 percent, and we require a 19 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. (Do not round your intermediate calculations.)

(b)	Calculate the worst-case NPV. (Do not round your intermediate calculations.)
