We are evaluating a project that costs $941,000, has a life of thirteen years, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at 119,000 units per year. Price per unit is $40, variable cost per unit is $22, and fixed costs are $952,292 per year. The tax rate is 22 percent, and we require a return of 21 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. Best case b. Calculate the worst-case NPV
