We are evaluating a project that costs $756,000, has a six-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 67,000 units per year. Price per unit is $41 variable cost per unit is $25, and fixed costs are $665,000 per year. The tax rate is 35 percent, and we require a return of 20 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) NPV for Best-case $__ NPV for Worst-case $__
