Consider a four-year project with the following information: initial fixed asset investment = $530,000; straight-line depreciation to zero over the four-year life; zero salvage value; price = $24; variable costs = $14; fixed costs = $170,000; quantity sold = 83,000 units; tax rate = 30 percent. How sensitive is OCF to changes in quantity sold? (Do not round intermediate calculations. Round your answer to 2 decimal places, e.g., 32.16.)
