Manufacturing overhead Direct labor Fabricating $ 353,500 Department Machining $ 404,000 Assembly $ 90,900 $ 202,000 $ 101,000 $ 303,000 Total Plant $ 848,400 $ 606,000 Jobs require varying amounts of work in the three departments. The Koopers job, for example, would have required manufacturing costs in the three departments as follows: Direct materials Direct labor Manufacturing overhead Required: Fabricating $ 3,200 $ 3,200 ? Department Machining $ 200 $ 500 ? Assembly $ 1,600 $ 6,400 ? Total Plant $ 5,000 $ 10,100 ? 1. Using the company's plantwide approach: a. Compute the plantwide predetermined rate for the current year. b. Determine the amount of manufacturing overhead cost that would have been applied to the Koopers job. 2. Suppose that instead of using a plantwide predetermined overhead rate, the company had used departmental predetermined overhead rates based on direct labor cost. Under these conditions: a. Compute the predetermined overhead rate for each department for the current year. b. Determine the amount of manufacturing overhead cost that would have been applied to the Koopers job. 4. Assume that it is customary in the industry to bid jobs at 150% of total manufacturing cost (direct materials, direct labor, and applied overhead). a. What was the company's bid price on the Koopers job using a plantwide predetermined overhead rate? b. What would the bid price have been if departmental predetermined overhead rates had been used to apply overhead cost?
