Consider a four-year project with the following information: initial fixed asset investment =$430,000; straight-line depreciation to zero over the four-year life; zero salvage value; price =$24; variable costs =$16; fixed costs =$120,000; quantity sold =72,000 units; tax rate =23 percent. How sensitive is OCF to changes in quantity sold? (Do not round intermediate calculations and round your answer to 2 decimal places, e.9., 32.16.)
