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 70% 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 30,000 curtain rods per year. A supplier offers to make a pair of finials at a price of $12.95 per unit. If Pottery Ranch accepts the supplier's offer, all variable manufacturing costs will be eliminated, but the $45,000 of fixed manufacturing overhead currently being charged to the finials will have to be absorbed by other products.
