Equivalent Units of Production: weighted average method

The Converting Department of Tender Soft Tissue Company uses the weighted average method and had 1,900 units in work in process that were 60% complete at the beginning of the period. During the period, 15,800 units were completed and transferred to the Packing Department. There were 1,200 units in process that were 30% complete at the end of the period.

a. Determine the number of whole units to be accounted

b. Determine the number of equivalent units of production for the period. Assume that direct materials are placed in process during production.
