We are evaluating a project that costs $116649, has a seven-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 4160 units per year. Price per unit is $50, variable cost per unit is $21, and fixed costs are $82736 per year. The tax rate is 30 percent, and we require a 10 percent return on this project. Suppose the projections given for price, quantity, variable costs, and fixed costs are all accurate to within +/-10 percent. What is the NPV of the project in worst-case scenario?
