问题如下:
Assuming periodic inventory system and weighted average cost method is adopted, in 2013, Company M purchased 2,000 units of inventory, each unit was bought at $50 and sold at $70, only 1500 units were sold. In 2014, it purchased another 1,000 units, each unit was bought at $60 and sold at $75, but only 500 units were sold. In 2014, the cost of sales is:
选项:
A.$16500
B.$28335
C.$43755
解释:
B is correct. In 2014, there are 500 units of inventory left by 2013, the weighted average cost = (500×50+1000×60)/(500+1000) = 56.67, cost of sales = 56.67×500 =28335
讲义公式里面公式的分子是可供出售的,2014年已经卖出了500, 可供出售的只剩下500了, 为什么题目在计算weighted average cost 的时候用了1000作为数量
