A suggested project requires initial fixed assets of $227,000, has a life of 4 years, and has no salvage value. Assume depreciation is straight-line to zero over the life of the project. Sales are projected at 31,000 units per year, the price per unit is $47, variable cost per unit is $23, and fixed costs are $842,900 per year. The tax rate is 23 percent, and the required return is 11.5 percent. Suppose the projections given for price and quantity can vary by pm 4 percent while variable and fixed cost estimates are accurate to within pm 2 percent. 

What is the best-case NPV?
