We are evaluating a project that costs $$875,000,$ has a life of twelve years, and has no salvage value. Assume that depreciation is straight$-$line to zero over the life of the project. Sales are projected at $143,000$ units per year. Price per unit is $$38,$ variable cost per unit is $$24,$ and fixed costs are $$893,375$ per year. The tax rate is $23$ percent, and we require a return of $13$ percent on this project. The projections given for price, quantity, variable costs, and fixed costs are all accurate to within $+/-18$ percent.
