The graph shows the amount of savings 3 children had.
- How much money must Irene give Rachel so that they will have the same amount of money?
- How much money must Opal give Rachel so that Rachel will have $2 more than her?
(a)
Irene's savings = $72
Rachel's savings = $16
Difference between Irene's and Rachel's savings
= 72 - 16
= $56
Amount that Irene must give Rachel
= 56 ÷ 2
= $28
(b)
Total amount of Opal and Rachel
= 48 + 16
= $64
2 u + 2 = 64
2 u = 64 - 2
2 u = 62
1 u = 62 ÷ 2 = 31
Amount that Opal must give to Rachel
= 48 - 31
= $17
Answer(s): (a) $28; (b) $17
