The graph shows the amount of savings 3 children had.
- How much money must Joelle give Betty so that they will have the same amount of money?
- How much money must Irene give Betty so that Betty will have $2 more than her?
(a)
Joelle's savings = $36
Betty's savings = $8
Difference between Joelle's and Betty's savings
= 36 - 8
= $28
Amount that Joelle must give Betty
= 28 ÷ 2
= $14
(b)
Total amount of Irene and Betty
= 24 + 8
= $32
2 u + 2 = 32
2 u = 32 - 2
2 u = 30
1 u = 30 ÷ 2 = 15
Amount that Irene must give to Betty
= 24 - 15
= $9
Answer(s): (a) $14; (b) $9
