A project costs $$2\mathrm{.}43$ million and has no salvage value. Depreciation is straight$-$line to zero

over the five$-$year life of the project. Sales are projected at $64,000$ units per year, price per unit

is $$73\mathrm{.}29,$ variable cost per unit is $$42\mathrm{.}93,$ and fixed costs are $$623,000$ per year. The tax rate is

$21$ percent, and the required rate of return is $11$ percent. What is the sensitivity of NPV to a
