Jobs 603 and 604 were started in June. Overhead cost is applied with a predetermined rate based on direct labor costs. Jobs 602 and 603 are finished in June, and Job 604 is expected to be finished in July. No raw materials are used indirectly in June. (Assume this company's predetermined overhead rate did not change over these months.) Required: 1. What is the cost of the raw materials used in June for each of the three jobs and in total? 2. How much total direct labor cost is incurred in June? 3. What predetermined overhead rate is used in June? 4. How much cost is transferred to finished goods inventory in June?
