Consider a four-year project with the following information: Initial fixed asset investment - $575,000; straight-line depreciation to zero over the four-year life; zero salvage value; price = $29; variable costs = $19, fixed costs $235,000; quantity sold 76,000 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.)
