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