Consider a three$-$year project with the following information: Initial fixed asset investment $=$ $$730,000$; straight$-$line depreciation to zero over the $6-$year life; zero salvage value; price $=$ $$39\mathrm{.}71$; variable costs $=$ $$28\mathrm{.}55$; fixed costs $=$ $$344,000$; quantity sold $=91,000$ units; tax rate $=23$ percent. How sensitive is OCF to changes in quantity sold?
