Erika received $58 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 Erika spent in Oct and in Dec?
- Write down all the months in which Erika spent more than half her allowance. Give the answer in short form. (Eg Jan, Mar)
(a)
Amount that Erika spent in Aug = $30
Amount that Erika spent in Sep = $23
Amount that Erika spent in Oct = $21
