Consider a three-year project with the following information: initial fixed asset investment = $670,000; straight-line depreciation to zero over the 4-year life; zero salvage value; price = $38.75; variable costs = $27.83; fixed costs = $308,000; quantity sold = 79,000 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.)
