We are evaluating a project that costs $$836,636,$ has an eight$-$year life, and has no salvage value. Assume that depreciation is straight$-$line to zero over the life of the project. Sales are projected at $55,027$ units per year. Price per unit is $$40,$ variable cost per unit is $$15,$ and fixed costs are $$423,091$ per year. The tax rate is $35\%,$ and we require a return of $19\%$ on this project.

In dollar terms, what is the sensitivity of OCF to changes in the variable cost per unit projection? $($Round answer to $2$ decimal places. Do not round intermediate calculations$)$
