Consider a four-year project with the following information: initial fixed asset investment = $570,000; straight-line depreciation to zero over the four-year life; zero salvage value; price = $30; variable costs = $22; fixed costs = $210,000; quantity sold = 87,000 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.)
