Jane 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 Jane spent in Jan and in Mar?
- Write down all the months in which Jane spent more than half her allowance. Give the answer in short form. (Eg Jan, Mar)
(a)
Amount that Jane spent in Nov = $55
Amount that Jane spent in Dec = $38
Amount that Jane spent in Jan = $24
Amount that Jane spent in Feb = $36
Amount that Jane spent in Mar = $45
Difference between the amounts Jane spent in Jan and Mar
= 45 - 24
= $21
(b)
Half of Jane's monthly allowance
= 80 ÷ 2
= $40
