Diewold Company has two departments, Milling and Assembly. The company uses a job-order costing system and computes a predetermined overhead rate in each department. The Milling Department bases its rat machine-hours, and the Assembly Department bases its rate on direct labor-hours. At the beginning of the year, the company made the following estimates: Direct labor-hours Machine-hours Total fixed manufacturing overhead cost Variable manufacturing overhead per machine-hour Variable manufacturing overhead per direct labor-hour Department Milling Assembly 6,100 $ $ 66,100 390,000 $ 3.00 90,000 2,700 502,000 - $ 3.75 Required: 1. Compute the predetermined overhead rate to be used in each department. (Round your answers to 2 decimal places.) Milling Predetermined overhead rate per MH Department Assembly per DLH 2. Assume that the overhead rates you computed in (1) above are in effect. The job cost sheet for Job 407, which was started and completed during the year, showed the following: Direct labor-hours Machine-hours Materials requisitioned Direct labor cost Milling Department 4 Assembly 13 84 5 750 $ 390 $ 39 $ 150 Compute the total manufacturing cost assigned to Job 407. (Round your intermediate and final answers to 2 decimal places.) Total manufacturing cost 3. Would you expect substantially different amounts of overhead cost to be charged to some jobs if the company used a plantwide overhead rate based on direct labor-hours instead of using departmental rates? 00 No Yes
