Sunland Bicycle Company manufactures its own seats for its bicycles. The company is currently operating at 100% capacity. Variable manufacturing overhead is charged to production at the rate of 60% of direct labor cost. The direct materials and direct labor cost per unit to make the bicycle seats are $8 and $9, respectively. Normal production is 47,000 bicycles per year. A supplier offers to make the bicycle seats at a price of $21 each. If the bicycle company accepts this offer, all variable manufacturing costs will be eliminated, but the $28,200 of fixed manufacturing overhead currently being charged to the bicycle seats will have to be absorbed by other products.
