Evans Products uses a process costing system with two processing departments: the Mixing Department and the Finishing Department. In June, unit costs incurred by the Mixing Department amounted to $4.00 per unit. Unit costs transferred to the finished goods warehouse during the month amounted to $22. Work-in-process inventories are reduced to zero each month. The transfer of 35,000 units to the Finishing Department in June required:

a. A debit to Finished Goods Inventory of $770,000.
b. A credit to Work-in-Process Inventory, Mixing Department of $770,000.
c. A credit to Work-in-Process Inventory, Finishing Department of $140,000.
d. A debit to Work-in-Process Inventory, Finishing Department of $140,000.

Cost incurred by mixing department is $4 which so the transfer of cost from mixing department to finishing department will be $140,000 for 35000 units. This cost will be recorded in the work in process inventory account of finishing department. As we know that WIP account has debit nature so same entry will be done to record an expense incurred in mixing department.
