The production department in a process manufacturing system completed 94,000 units of product and transferred them to finished goods during a recent period. Of these units, 28,200 were in process at the beginning of the period. The other 65,800 units were started and completed during the period. At period-end, 16,700 units were in process. Compute the departments equivalent units of production with repect to direct materials under each of three seperate assumptions, using the weighted average method, then using the FIFO method a. All direct materials are added to products when processing begins.
b. Beginning inventory is 40% complete to materials and conversion costs. Ending inventory is 75% complete as to materials and conversion costs
c. Beginning inventory is 60% complete as to materials and 40% complete as to conversion costs. Ending Inventory is 30% complete as to materials and 60% complete to conversion costs.

Weighted Average Method.

a. 110,700 units

b.  106,525 units

c.  82,090 units

FIFO

a. 85,500 units

b.  95,245 units

c.  99,010 units

Explanation:

Calculation of equivalent units of production with respect to direct materials.

FIFO.

a. All direct materials are added to products when processing begins.

1) the stages a new product goes through from beginning to end, i.e., the stages that a product passes through from introduction through growth, maturity, and decline. 2) the time from initial research and development to the time at which sales and support of the product to customers are withdrawn. 3) the period of time during which a product can be produced and marketed profitably.
