Conversion
Transferred to next department*
380,000
380,000
Ending work in process:
Materials: 40,000 units x 75% complete 30,000
Conversion: 40,000 units x 25% complete
10,000
Equivalent units of production
410,000
390,000
*Units transferred to the next department = Units in beginning work in process + Units started into production − Units in ending work in process = 70,000 + 350,000 − 40,000 = 380,000
