Consider a four-year project with the following information: initial fixed asset investment = $500,000; straight-line depreciation to zero over the four-year life; zero salvage value; price = $35; variable costs = $26; fixed costs = $200,000; quantity sold = 80,000 units; tax rate = 25 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.)
