Consider a four-year project with the following information: Initial fixed asset investment = $655,000; straight-line depreciation to zero over the four-year life; zero salvage value; price = $28; variable costs = $16; fixed costs = $245,000; quantity sold = 61,000 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.)
