The graph shows the amount of savings 3 children had.
- How much money must Xandra give Jean so that they will have the same amount of money?
- How much money must Mary give Jean so that Jean will have $2 more than her?
(a)
Xandra's savings = $90
Jean's savings = $20
Difference between Xandra's and Jean's savings
= 90 - 20
= $70
Amount that Xandra must give Jean
= 70 ÷ 2
= $35
(b)
Total amount of Mary and Jean
= 60 + 20
= $80
2 u + 2 = 80
2 u = 80 - 2
2 u = 78
1 u = 78 ÷ 2 = 39
Amount that Mary must give to Jean
= 60 - 39
= $21
Answer(s): (a) $35; (b) $21
