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