Job Order Costing Problems

Problem 1: Dalton Manufacturing uses a job order costing system. On May 1, the company had a balance in the Work in Process Inventory account of $3200 (all direct materials). There were two jobs in process--Job 429 with DM of $2000 and Job 430 with DM of $1200. During the month of May, the following costs were incurred.

Job Number

429
$2,500
$2,400
430
3,500

431
4,400
7,600
General Use (MO)
800
1,200
Totals

$14,200

Dalton applies overhead at the rate of 90% of Direct Labor Cost. Job 429 was completed during the month.

Required:

1. Prepare journal entries to record the requisitioning of direct materials, the labor costs, and the assignment of manufacturing overhead to jobs. Also record the completion of Job 429.

2. Prepare the job cost sheets and prove the agreement of Work in Process with the job cost sheets.
