We are evaluating a project that costs $732,000, has a six-year lfe, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at 55,000 units per year Price per unit is $60, variable cost per unit is $30, and fixed costs are $640,000 per year. The tax rate is 35 percent, and we require a return of 12 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. (Negative amounts should be indicated by a inus sign. Do not round intermediate calculations and round your final answers to 2 decim places, e.g., 32.16.] NPV Best-case Worst-case
