We are evaluating a project that costs $1.68 million, has a five-year life, and has no salvage value. Assume depreciation is straight-line to zero over the life of the project. Sales are projected at 82,000 units per year. Price per unit is $43.29, variable cost per unit is $22.18, and fixed costs are $623,000 per year. The tax rate is 34 percent, and we require a 10 percent return on this project. What is the sensitivity of NPV to a 100-unit change in the sales figure? $3,998.40 $4,609.18 $4,897.20 $5,281.55 $5,557.12
