【正确答案】
C
【答案解析】Average cost per unit purchased:
40 units at $ 60/per unit = $ 2400
50 units at $ 55/per unit = $ 2750
60 units at $ 45/per unit = $ 2700
Total = 150 units = $ 7850
Average cost per unit = $ 7850/150 units = $ 52.33/unit
Purchased 40 +50 +60 = 150 units. Sold 25 +30 +40 =95
Ending inventory = ( 150 - 95 ) × 52.33/unit = 55 units × $ 52.33/unit = $ 2878
