We are evaluating a project that costs $2,130,000, has a 8-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 90,600 units per year. Price per unit is $38.85, variable cost per unit is $23.95, and fixed costs are $860,000 per year. The tax rate is 25 percent, and we require a return of 11 percent on this project. Suppose the projections are given for price, quantity, variable costs, and fixed costs are all accurate to within ±10 percent. Calculate the best-case and worst-case NPV figures. (A negative answer should be indicated by a minus sign. Do not round intermediate calculations and round your answers to 2 decimal places, e. g. 32.16.)
