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