Autovalet Manufacturing uses a job order cost system in each of its three manufacturing departments. Manufacturing overhead is applied to jobs on the basis of direct labour cost in Department A, direct labour hours in Department B and machine hours in Department C. The following estimates were used in establishing the predetermined overhead rates for 2014: Department
A B C
Manufacturing Overhead $840,000 $902,000 $850,000
Direct Labour Cost $600,000 $100,000 $600,000
Direct Labour Hours 50,000 41,000 50,000
Machine Hours 100,000 120,000 170,000

 

 

(a) Calculate the predetermined overhead rate for each department. (4 marks)

(b) During January 2014, the job cost sheets showed the following costs and production data:

Direct Labour Hours 4,000 3,500 4,200
Machine Hours 8,000 10,500 12,800
Manufacturing overhead incurred $78,000 $69,500 $67,200

 

Calculate the total manufacturing cost assigned to jobs in January in each department.

(c) Calculate the overhead variance for each department at January 31. (4½ marks)

 

(d) Using the total figures, record the journal entries for:

  1. i) Total direct materials used

  • Cost of the units in the Programming Department ending work in process inventory

 

(6½ marks)

iii) Present the journal entries to record the assignment of direct materials and direct labour and the allocation of manufacturing overhead to the Programming Process. Also give the journal entry to record the cost of the units completed and transferred out to Packing. (3 marks)
