We are evaluating a project that costs $684800, has a five-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 47566 units per year. Price per unit is $46, variable cost per unit is $26, and fixed costs are $521950 per year. The tax rate is 30%, and we require a return of 20% on this project. Suppose the projections given for price, quantity, variable costs, and fixed costs are all accurate to within ±10 percent.
