Consider a four-year project with the following information: initial fixed asset investment = $615,000; straight-line depreciation to zero over the four-year life; zero salvage value; price = $49; variable costs = $37; fixed costs = $290,000; quantity sold = 115,000 units; tax rate = 21 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.)
