Problem $2$:

We are evaluating a project that costs $$644,000,$ has an eight$-$year life, and has no salvage value. Assume that depreciation is straight$-$line to zero over the life of the project. Sales are projected at $70,000$ units per year. Price per unit is $$37,$ variable cost per unit is $$21,$ and fixed costs are $$725,000$ per year. The tax rate is $35$ percent, and we require a $15$ percent return on this project. Suppose the projections given for price, guantity, variable costs, and fixed costs are all accurate to within $-10$ percent. Calculate the best$-$case and worst$-$case NPV figures.
