Answer: $113,120
Step-by-step explanation:
Direct material used = Total cost of manufacturing - Direct labor - Factory overhead
Total cost of manufacturing = Ending WIP + Cost of manufacturing - Beginning WIP
= 131,040 + 324,800 - 100,800
= $355,040
Direct labor = Factory overhead * 100/60
= 90,720 * 100/60
= $151,200
Direct materials used = 355,040 - 151,200 - 90,720
= $113,120
