Final answer:
To determine the amount of direct materials charged to Job 250, you need to use the predetermined overhead rate of 90% based on direct labor cost. The manufacturing overhead charged to Job 250 is $8,100, and the direct materials charged to Job 250 can be calculated as $900.
Step-by-step explanation:
To determine the amount of direct materials charged to Job 250, we need to use the predetermined overhead rate of 90% based on direct labor cost. The manufacturing overhead charged to Job 250 is $8,100. Therefore, the direct labor cost incurred for Job 250 can be calculated as follows:
Direct Labor Cost = Manufacturing Overhead / Predetermined Overhead Rate
Direct Labor Cost = $8,100 / 0.90 = $9,000
Since the predetermined overhead rate is based on direct labor cost, we can use this information to find the direct materials charged to Job 250. If we assume that the direct labor cost is 100%, then the direct materials charged can be calculated using the formula:
Direct Materials Charged = Direct Labor Cost * Direct Materials Percentage
Direct Materials Charged = $9,000 * (1 - Predetermined Overhead Rate)
Direct Materials Charged = $9,000 * (1 - 0.90)
Direct Materials Charged = $9,000 * 0.10 = $900
