We are evaluating a project that costs $832,000, 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 40,000 units per year. Price per unit is $40, variable cost per unit is $17, and fixed costs are $700,000 per year. The tax rate is 23 percent and we require a return of 13 percent on this project. Suppose the projections 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.)
