Pharoah Ranch Inc. has been manufacturing its own finials for its curtain rods. The company is currently operating at $100\%$ of capacity, and variable manufacturing overhead is charged to production at the rate of $57\%$ of direct labor cost. The direct materials and direct labor cost per unit to make a pair of finials are $$4$ and $$5,$ respectively. Normal production is $35,000$ curtain rods per year.

A supplier offers to make a pair of finials at a price of $$12\mathrm{.}80$ per unit. If Pharoah Ranch accepts the supplier's offer, all variable manufacturing costs will be eliminated, but the $$46,700$ of fixed manufacturing overhead currently being charged to the finials will have to be absorbed by other products.
