Pottery 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 56% of direct labor cost. The direct materials and direct labor cost per unit to make a pair of finials are $3.72 and $4.86, respectively. Normal production is 25,800 curtain rods per year. A supplier offers to make a pair of finials at a price of$13.31 per unit. If Pottery Ranch accepts the supplier's offer, all variable manufacturing costs will be eliminated, but the $46,100 of fixed manufacturing overhead currently being charged to the finials will have to be absorbed by other products.
