Consider a four$-$year project with the following information: Initial fixed asset investment $=$ $$565,000$; straight$-$line depreciation to zero over the four$-$year life; zero salvage value; price $=$ $$39$; variable costs $=$ $$24$; fixed costs $=$ $$240,000$; quantity sold $=85,000$ 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$.,32\mathrm{.}16.)$
