Final answer:
The correct entry to record the transfer of materials is to debit Work In Process Inventory for $66,000, debit Manufacturing Overhead for $9,000, and credit Raw Materials Inventory for $75,000, which represents the combined cost of direct and indirect materials.
Step-by-step explanation:
The correct journal entry to record the transfer of materials from the storeroom to their respective places in the production process is the one that debits (Work In Process Inventory) for the direct materials used and debits (Manufacturing Overhead) for the indirect materials used, while crediting (Raw Materials Inventory) for the total amount of materials requisitioned. Therefore, the correct entry is:
d. Work In Process Inventory.................................................... 66,000
Manufacturing Overhead....................................................... 9,000
Raw Materials Inventory.............................................. 75,000
This entry reflects the usage of $66,000 in direct materials directly attributable to the product being manufactured and $9,000 in indirect materials which are part of the manufacturing overhead costs.
