We are evaluating a project that costs $2,190,000, has a life of 8 years, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at 91,200 units per year. Price per unit is $38.97, variable cost per unit is $24.05, and fixed costs are $866,000 per year. The tax rate is 22 percent, and we require a return of 11 percent on this project Suppose the projections given for price, quantity, variable costs, and fixed costs are all accurate to within 110 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.) OCF NPV Best-case Worst-case
