The most likely outcomes for a particular project are estimated as follows:

Unit price:$70Variable cost:$50Fixed cost:$300,000Expected sales:40,000units per year

However, you recognize that some of these estimates are subject to error. Suppose that each variable may turn 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 $2.2 million, which will be depreciated straight-line over the project life to a final value of zero. The firm's tax rate is 30% and the required rate of return is 12%.

a.What is project NPV in the best-case scenario, that is, assuming all variables take on the best possible value?(A negative amount should be indicated by a minus sign. Enter your answer in dollars not in millions. Do not round intermediate calculations. Round your answerto the nearest dollar amount.)
