We are evaluating a project that costs $619,500, has a seven-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 90,000 units per year. Price per unit is $43, variable cost per unit is $30, and fixed costs are $705,000 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 10 percent.
