We are evaluating a project that costs $1,120,000, has a life of 10 years, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at 35,000 units per year. Price per unit is $50, variable cost per unit is $25, and fixed costs are $620,000 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 \pm 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.)
