(No. of equivalent units of conversion x cost per equivalent unit of conversion)

1,800 x $1.11 $1,998

Total cost of April 30 work in process $4,854

Note: Cost of goods completed and transferred out during April + Total cost of April 30 work in process should be equal to total costs to account for. However, due to the calculation, there may be small difference in total number.

b) Show the flow of costs through the WIP Inventory T-account.
