A company has the following estimates for a new five-year project: Cost of machine - $500,000, price - $900 per unit, variable cost-$80 per unit, fixed costs - $390,000, and quantity - 5,000 units. Suppose the company believes that all of these estimates are accurate only to within plus or minus 15 percent.
