We are evaluating a project that costs $845,000, has a life of nine years, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at 134,000 units per year. Price per unit is $41, variable cost per unit is $28, and fixed costs are $849,225 per year. The tax rate is 21 percent, and we require a return of 18 percent on this project. The projections given for price, quantity, variable costs, and fixed costs are all accurate to within +/- 19 percent. a. Calculate the best-case NPV. b. Calculate the worst-case NPV
