Consider a four$-$year project with the following information: Initial fixed asset investment $=$ $$655,000$; straight$-$line depreciation to zero over the four$-$year life; zero salvage value; price $=$ $$28$; variable costs $=$ $$16$; fixed costs $=$ $$245,000$; quantity sold $=61,000$ units; tax rate $=21$ percent.

How sensitive is OCF to changes in quantity sold? $($Do not round intermediate $OCF\frac{?}{?}Q=$
