The graph shows the amount of savings 3 children had.
- How much money must Irene give Xuan so that they will have the same amount of money?
- How much money must Gwen give Xuan so that Xuan will have $4 more than her?
(a)
Irene's savings = $72
Xuan's savings = $16
Difference between Irene's and Xuan's savings
= 72 - 16
= $56
Amount that Irene must give Xuan
= 56 ÷ 2
= $28
(b)
Total amount of Gwen and Xuan
= 48 + 16
= $64
2 u + 4 = 64
2 u = 64 - 4
2 u = 60
1 u = 60 ÷ 2 = 30
Amount that Gwen must give to Xuan
= 48 - 30
= $18
Answer(s): (a) $28; (b) $18
