Answer:
completed units = 9,500 gallons
Step-by-step explanation:
gallons completed = beginning WIP inventory + units started during the month - ending WIP inventory = 1,000 gallons + 10,000 gallons - 1,500 = 9,500 gallons finished
units started and completed = total units started -ending WIP = 10,000 gallons - 1,500 gallons = 8,500 gallons
