Consider a 3-year project with the following information: initial fixed asset investment = $770,000; straight-line depreciation to zero over the 3-year life; zero salvage value; price = $34.99; variable costs = $23.16; fixed costs = $245,000; quantity sold = 94,500 units; tax rate = 35 percent. How sensitive is OCF to an increase of one unit in the quantity sold?
