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