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