Ferrish Industries has an annual plant capacity of $67,000$ units; current production is $54,000$ units per year. At the current production volume, the variable cost per unit is $$35\mathrm{.}00$ and the fixed cost per unit is $$4\mathrm{.}60.$ The normal selling price of Ferrish's product is $$47\mathrm{.}00$ per unit. Ferrish has been asked by Cornhill Company to fill a special order for $7,000$ units of the product at a special sales price of $$27\mathrm{.}00$ per unit. Cornhill is located in a foreign country where Ferrish does not currently operate. Cornhill will market the units in its country under its own brand name, so the special order is not expected to have any effect on Ferrish's regular sales.
