Cost Accounting Chapter 17 Solutions
CHAPTER 17
PROCESS COSTING
17-16 (25 min.) Equivalent units, zero beginning inventory.
1. Direct materials cost per unit ($750,000 ÷ 10,000) $ 75.00 Conversion cost per unit ($798,000 ÷ 10,000) 79.80 Assembly Department cost per unit $154.80
2a. Solution Exhibit 17-16A calculates the equivalent units of direct materials and conversion costs in the Assembly Department of Nihon, Inc. in February 2009. Solution Exhibit 17-16B computes equivalent unit costs.
2b. Direct materials cost per unit $ 75 Conversion cost per unit 84 Assembly Department cost per unit $159
3. The difference in the Assembly Department cost per unit calculated in requirements 1 and 2 arises because the costs incurred in January and February are the same but fewer equivalent units of work are done in February relative to January. In January, all 10,000 units introduced are fully completed resulting in 10,000 equivalent units of work done with respect to direct materials and conversion costs. In February, of the 10,000 units introduced, 10,000 equivalent units of work is done with respect to direct materials but only 9,500 equivalent units of work is done with respect to conversion costs. The Assembly Department cost per unit is, therefore, higher.
