You are considering a new product launch. The project will cost $$840,000,$ have a $4-$year life, and have no salvage value; depreciation is straight$-$line to zero. Sales are projected at $500$ units per year, price per unit will be $$18,600,$ variable cost per unit will be $$15,300,$ and fixed costs will be $$860,000$ per year. The required return on the project is $11$ percent, and the relevant tax rate is $22$ percent.

The unit sales, variable cost, and fixed cost projections given above are probably accurate to within $\backslash$pm $10$ percent. What are the upper and lower bounds for these projections? What is the base$-$case NPV$?$ What are the best$-$case and worst$-$case scenarios?
