Assume that RamCo applies overhead to jobs based on direct labor cost. Job A1 was started and completed and sold to customer for $500. The Job A1 cost sheet shows $200 for direct materials, $100 for direct labor, and $60 for overhead on its job cost sheet. Job A2 is still in process at year end and shows charges of $280 for direct materials and $150 for direct labor. How much overhead should be charged to Job A2 at year end?
