Required:
1. What was the cost of raw materials put into production during the year?
2. How much of the materials in (1) above consisted of indirect materials?
3. How much of the factory labor cost for the year consisted of indirect labor?
4. What was the cost of goods manufactured for the year?
5. What was the cost of goods sold for the year (before considering underapplied or overapplied overhead)?
6. If overhead is applied to production on the basis of direct materials cost, what rate was in effect during the year?
7. Was manufacturing overhead underapplied or overapplied? By how much?
8. Compute the ending balance in the Work in Process inventory account. Assume that this balance consists entirely of goods started during the year. If $32,000 of this balance is direct materials cost, how much of it is direct labor cost? Manufacturing overhead cost?

SOLUTION:

1. The cost of raw materials put into production was:

|Raw materials inventory, 1/1 |$ 30,000 |

|Raw materials inventory, 12/31 | 60,000 |
|Materials requisitioned for production |$390,000 |
| | |

2. Of the $390,000 in materials requisitioned for production, $320,000 was debited to Work in Process as direct materials. Therefore, the difference of $70,000 ($390,000 – $320,000 =
