Consider a four-year project with the following information: initial fixed asset investment = $520,000; straight-line depreciation to zero over the four-year life; zero salvage value; price = $22; variable costs = $12; fixed costs = $160,000; quantity sold = 82,000 units; tax rate = 22 percent. How sensitive is OCF to changes in quantity sold? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.)
