Heidelberg Fabrication manufactures two products, G-09 and G-35: Units produced Direct materials cost per unit Machine-hours per unit G-09 18,900 G-35 3,780 $7 $ 19 4 144 7 72 Production runs per quarter: Production at the plant is automated and any labor cost is included in overhead. Data on manufacturing overhead at the plant follow: Machine depreciation Setup labor Materials handling Total $ 102,060 51,030 40,824 $193,914 Required: a. Heidelberg currently applies overhead on the basis of machine-hours. What is the predetermined overhead rate for the quarter? Note: Round your answer to 2 decimal places. b. Heidelberg is thinking of adopting an ABC system. They have tentatively chosen the following cost drivers: machine-hours for machine depreciation, production runs for setup labor, and direct material dollars for materials handling. Compute the cost driver rates for the proposed system at Heidelberg. a. Overhead rate b. Machine depreciation b. Setup labor b.
