How will you calculate the costs assigned to the work in process inventory?

Cost Assigned to Work in Process Inventory. The manager of a company whose manufacturing process lends itself quite readily to process costing methods approached the accountant with the request to compute, for his study and consideration, the work in process inventory on (a) the average cost basis and (b) the first-in, first-out basis. The following data are available
:
Units in opening inventory, 8,000; all materials, 50% labor and overhead.
Cost of opening inventory: Materials, $3,984; Labor, $2,148; Overhead, $1,692.
Placed in process, 40,000 units. Cost: Materials, $24,000; Labor, $19,968; Overhead, $19,968.
 

Units completed and transferred, 42,000.
Units in process at the end, 6,000; all materials, 60% labor and overhead.

Required: The costs assigned to the work in process inventory.
