The graph shows the amount of savings 3 children had.
- How much money must Risa give Usha so that they will have the same amount of money?
- How much money must Kylie give Usha so that Usha will have $2 more than her?
(a)
Risa's savings = $36
Usha's savings = $8
Difference between Risa's and Usha's savings
= 36 - 8
= $28
Amount that Risa must give Usha
= 28 ÷ 2
= $14
(b)
Total amount of Kylie and Usha
= 24 + 8
= $32
2 u + 2 = 32
2 u = 32 - 2
2 u = 30
1 u = 30 ÷ 2 = 15
Amount that Kylie must give to Usha
= 24 - 15
= $9
Answer(s): (a) $14; (b) $9
