Answer:
Beginning Raw material Inventory = Direct materials used - Raw Materials purchases + Ending raw materials inventory
= 188,420 - 159,120 + 22,610
= $51,910
Total cost of work in process = Cost of goods manufactured + Work in process (12/31)
= 544,240 + 83,230
= $627,470
Total Manufacturing costs = Total cost of work in process - Work in process (1/1)
= 627,470 - 220,940
= $406,530
Direct labor = Total Manufacturing costs - Total overhead - Direct materials used
= 406,530 - 139,320 - 188,420
= $78,790
