The graph shows the amount of savings 3 children had.
- How much money must Kathy give Yen so that they will have the same amount of money?
- How much money must Risa give Yen so that Yen will have $4 more than her?
(a)
Kathy's savings = $36
Yen's savings = $8
Difference between Kathy's and Yen's savings
= 36 - 8
= $28
Amount that Kathy must give Yen
= 28 ÷ 2
= $14
(b)
Total amount of Risa and Yen
= 24 + 8
= $32
2 u + 4 = 32
2 u = 32 - 4
2 u = 28
1 u = 28 ÷ 2 = 14
Amount that Risa must give to Yen
= 24 - 14
= $10
Answer(s): (a) $14; (b) $10
