单选题 An analyst does research about inventory methods. A company with no initial inventory on hand made the following purchases of inventory in 2011:
Period Number of Units Price Per Unit
1 7000 $76
9 10100 $80
3 8000 $91
At the end of 2011, the company had 5000 units of inventory on hand. Under a periodic inventory system, ending inventory using the weighted average cost method is closest to:
A. $43000 less than using the FIFO method.
B. $32000 more than using the FIFO method.
C. $43000 more than using the FIFO method.

【正确答案】 A
【答案解析】[解析] average price of one unit=(7000×$76+10100×$80+8000×$91)/(7000+10100+8000)=$82.4。
inventory(weighted average cost)=5000×$82.4=$412000。
inventory(FIFO)=5000×$91=$455000。
inventory(weighted average cost)-inventory(FIFO)=$412000-$455000=-$43000。
