Answer and Explanation:
The journal entry to record the flow of cost into department 3 is shown below
Work in Process - Department 3 $555,000
To Work in Process - Department 2 $555,000
(Being the flow of cost into department 3 is recorded)
For recording this we debited the work in process in department 3 as there is a flow and credited the work in process in department 2
The amount is came from
= $100,000 + $125,000 + $150,000 + $50,000 + $60,000 + $70,000
= $555,000
