完整解法

1. Relate the number of unsold items to the number of sold items

Since the starting quantity for all items is the same ( $66$ ), the item with the most number left unsold is the one with the least number sold.

2. Identify the item with the least number sold from the bar graph

From the bar graph, the shortest bar corresponds to the item with the least number sold. The shortest bar is for 'Notebook' ( $34$ items sold).

答案

Notebook

1. Read the number of pens sold from the bar graph

From the bar graph, the number of pens sold is $56$ .

2. Calculate the total money collected from selling the pens

Total money collected = $56 \times \char36{}1.95 = \char36{}109.20$

答案

$109.20
