Expected sales: $,48,000$ units per year

However, you recognize that some of these estimates are subject to error. Suppose each variable turns out to be either $10\%$ higher or

$10\%$ lower than the initial estimate. The project will last for $10$ years and requires an initial investment of $$2\mathrm{.}3$ million, which will be

depreciated straight$-$line over the project life to a final value of zero. The firm's tax rate is $21\%,$ and the required rate of return is $10\%.$

a$.$ What is project's NPV in the best$-$case scenario, that is$,$ assuming all variables take on the best possible value?

b$.$ What is project's NPV in the worst$-$case scenario?

Note: For all the requirements, a negative amount should be indicated by a minus sign. Enter your answers in dollars, not in

millions. Do not round intermediate calculations. Round your answers to the nearest dollar amount.

a$.$ NPV
