Answer:
The correct option is:
Work in Process 4,000 Materials 4,000
Explanation:
The total cost of the part= $2.50*1,600 units
The total cost of the part=$4,000
Going by the rule of the double which requires receiving account to debited while giving account is credited, we debit work-in-process with $4,000 while materials(inventory in the balance sheet) is credited with the same amount of $4,000.
