Answer:
a. $283,140
Explanation:
equivalent units: complete untis + percentage of completion ending units
(notice there is no beginning inventory)
18,000 complete + 2,000 x 100% = 20,000 materials
18,000 complete + 2,000 x 30% = 18,600 conversion cost
equivalent cost: 100,000 / 20,000 = 5
conversion cost: (142,300 + 57,200) / 18,600 = 10,72580 = 10.73
total unit cost: 15.73
transferred-out units: 18,000 x 15.73 = 283.140
