Shiyun received $84 from her father each month for her pocket money. The line graph shows the amount of pocket money she spent each month.
- What is the difference between the amounts Shiyun spent in Mar and in May?
- Write down all the months in which Shiyun spent more than half her pocket money. Give the answer in short form. (Eg Jan, Mar)

Amount that Shiyun spent in Jan = $52
Amount that Shiyun spent in Feb = $26
Amount that Shiyun spent in Mar = $42
Amount that Shiyun spent in Apr = $22
