Question:

Grange Company has two departments. Stamping and Assembly. The company uses a job-order costing system and computes a predetermined overhead rate in each department. The Stamping Department bases its rate on machine-hours, and the Assembly Department bases its rate on direct labour cost. At the beginning of the year, the company made the following estimates:

Department Stamping Assembly 40,000 Direct labour-hours Machine-hours. ... Manufacturing overhead cost. 125,000 15,000 $


Required

1. Compute the predetermined overhead rate to be used in each department.

2. Assume that the overhead rates you computed in (I) above are in effect. The job cost sheet for Job 407, which was started and completed during the year, shows the following:

Department Stamping Assembly Direct labour-hours . 25 100 Machine-hours.... Materials requisitioned... Direct labour cos


Compute the total overhead cost applied to Job 407.

3. Would you expect substantially different amounts of overhead cost to be charged to some jobs if the company used a plant wide overhead rate based on direct labour cost instead of using departmental rates? Explain. No computations are necessary.
