Sanders Toys is beginning to manufacture Bungey Wagons. The product will be sold to toy store chains for $12 each. Management allocates $120,000 of fixed manufacturing overhead costs to Bungey Wagons. The manufacturing cost for each wagon at the expected production of 10,000 wagons is as follows: Direct material Direct labor Overhead ($1.20 fixed and $2.00 variable) Total $ 13.00 4.00 3.20 $20.20 The company has contacted a number of suppliers to determine whether it is better to buy or manufacture the wheels. The lowest quote for a set of 4 wheels needed for each wagon is $3.15. It is estimated that purchasing the wheels from a supplier will save 10 percent of direct materials, 20 percent of direct labor, and 15 percent of variable overhead.
