Xeno, Inc. operates a process costing system and uses the FIFO method. Beginning work in process consists of 1,000 units, 30% complete. Ending work in process is 15% complete, and direct materials are added at the 20% point. The equivalent units of production for materials are 14,000 and for conversion costs are 18,000. The number of units in ending work in process was

A)22,000

B) 14,000

I think it is answer A, but I am not a hundred percent sure.
