We are evaluating a project that costs $$922,000,$ has a life of thirteen years, and has no salvage value. Assume that depreciation is straight$-$line to zero over the life of the project. Sales are projected at $111,000$ units per year. Price per unit is $$44,$ variable cost per unit is $$26,$ and fixed costs are $$926,610$ per year. The tax rate is $24$ percent, and we require a return of $12$ percent on this project. The projections given for price, quantity, variable costs, and fixed costs are all accurate to within $+/-14$ percent.
