Answer: 770,000 units
Step-by-step explanation:
The Equivalent units for Conversion cost is calculated as:
= Total units completed and transferred out + Equivalent units of closing work in process
As the conversion costs were incurred uniformly during the process, the entire closing work in process would have already incurred conversion cost. Conversion cost closing equivalent units are therefore 80,000 units.
Equivalent units for Conversion cost = 690,000 + 80,000
= 770,000 units
