Kylie received $80 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 Kylie spent in Sep and in Nov?
- Write down all the months in which Kylie spent more than half her allowance. Give the answer in short form. (Eg Jan, Mar)
(a)
Amount that Kylie spent in Jul = $52
Amount that Kylie spent in Aug = $39
Amount that Kylie spent in Sep = $20
Amount that Kylie spent in Oct = $31
