Answer:
42,100 tons
Step-by-step explanation:
Units Completed = Beginning Work in Process Units Completed + Units started & Completed during October
54,000 = 11,900 + Units started & Completed during October
Units started & Completed during October = 54,000 - 11,900
Units started & Completed during October = 42,100
So, the number of tons were started and completed during October is 42,100 tons.
