We are evaluating a project that costs $$500,000,$ has a life of $8$ years, and has no salvage value. Assume that depreciation is straight$-$line to zero over the life of the project. Sales are projected at $50,000$ units per year. Price per unit is $$40,$ variable cost per unit is $$25,$ and fixed costs are $$600,000$ per year. The tax rate is $22$ percent, and we require a return of $12$ 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. $($A negative answer should be indicated by a minus sign. Do not round intermediate calculations and round your answers to $2$ decimal places, e$.$g$.,32\mathrm{.}16.)$
