Question

The Converting Department of Osaka Napkin Company uses the average cost method and had 2,000 units in work in process that were 60% complete at the beginning of the period. During the period, 25,200 units were completed and transferred to the Packing Department. There were 1,100 units in process that were 30% complete at the end of the period.
a. Determine the number of whole units to be accounted for and to be assigned costs for the period.

b. Determine the number of equivalent units of production for the period.

Answer 1

Answer:

Equivalent Units

Material cost = 26,560

Conversion Cost= 25,540

Explanation:

We would assume the company uses  weighted average method of valuation.

Under the weighted average method of valuation, to account for completed units, it is assumed that the entire degree of work required is done in the period under consideration. So there is no separation of the completed units into opening inventory and fully worked.

Equivalent units = Degree of completion (%) × Number of units

Material cost

Item                                 Unit                                  Equivalent unit

Completed                    25,200      100% ×25200  = 25,200

Closing WIP                   1,360           100%× 1,360       1360

Total equivalent units                                                 26,560

Conversion Cost

Item                                 Unit                                  Equivalent unit

Completed                    25,200      100% ×25200  = 25,200

Closing WIP                   1,360           25%× 1,360        340

Total equivalent units
