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