The most likely outcomes for a particular project are estimated as follows:Unit price:$ 50 Variable cost:$ 30 Fixed cost:$ 300,000 Expected sales:30,000units per yearHowever, 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 $1 million, which will be depreciated straight-line over the project life to a final value of zero. The firms tax rate is 21%, and the required rate of return is 12%.What is the project's NPV in the best-case scenario, that is, assuming all variables take on the best possible value?What is the project's NPV in the worst-case scenario
