A project under consideration costs $750,000, has a five-year life, and has no salvage value. Depreciation is straight-line to zero. The required return is 17%, and the tax rate is 21%. Sales are projected at 500 units per year. Price per unit is $2,500, variable cost per unit is $1,500, and fixed costs are $200,000 per year. Suppose you think that the unit sales, price, variable cost, and fixed cost projections given here are accurate to within 5%. What are the upper and lower bounds for these projections? What is the base-case NPV? What are the best- and worst-case scenario NPVs? Hint: it is about scenario analysis
