Red Company has two departments: cutting and finishing. The company uses a job-order costing system and computes a predetermined overhead rate in each department. The cutting department bases its rate on machine-hours, and the finishing department bases its rate on lirect labour cost. At the beginning of the year, the company made the following estimates: 1. Compute the predetermined overhead rate to be used in each department. 2. Assume that the overhead rates that you computed in Requirement (1) are in effect. The job cost sheet for job 129, which was started and completed during the year, showed the following: Compute the total overhead cost applied to job 129. 3. Would you expect substantially different amounts of overhead cost to be assigned to some jobs if the company used a plantwide overhead rate based on direct labour cost, rather than using departmental rates? Explain your answer. No computations are necessary
