Answer: 27,000 units
Step-by-step explanation:
Equivalent Units of Production are used when units produced are not yet completed but costs still need to be assigned to them. They will therefore be treated as completed units according to the percentage of completion that they are at.
Equivalent Units of Production = Units transferred out + % complete Ending Work in Process units
= 15,000 + ( 80% * 15,000)
= 27,000 units
