E6-47B Compute equivalent units using the weighted average method and assign costs (Learning Objectives 2, 3, & 4) The Assembly Department of Best Surge Protectors began September with no work in process inventory. During the month, production that cost $41,400 (direct materials, $9,000, and conversion costs, $32,400) was started on 22,000 units.

Assign the costs to units completed and transferred out and ending work in process inventory. 4. Record the journal entry for the costs transferred out of the Assembly Department to the Testing Department. 5. Post all of the transactions in the Work in Process Inventory-Assembly T-account.
