We are evaluating a project that costs $$2,160,000,$ has a $8-$year life, and has no salvage value. Assume that depreciation is straight$-$line to zero over the life of the project. Sales are projected at $90,900$ units per year. Price per unit is $$38\mathrm{.}91,$ variable cost per unit is $$24\mathrm{.}00,$ and fixed costs are $$863,000$ per year. The tax rate is $21$ 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 $\backslash$pm $10$ percent.$$Calculate the best$-$case and worst$-$case NPV figures.
