Sarah received $68 from her father each month for her allowance. The line graph shows the amount of allowance she spent each month.
- What is the difference between the amounts Sarah spent in Dec and in Feb?
- Write down all the months in which Sarah spent more than half her allowance. Give the answer in short form. (Eg Jan, Mar)
(a)
Amount that Sarah spent in Oct = $45
Amount that Sarah spent in Nov = $32
Amount that Sarah spent in Dec = $21
Amount that Sarah spent in Jan = $31

Difference between the amounts Sarah spent in Dec and Feb

Half of Sarah's monthly allowance
