Esther and Oliver had the same amount of money at first. After Esther spent $55 on a wallet and Oliver received $75 from his aunt, Oliver had 3 times as much as money as Esther. How much money did Esther have at first?
| |
Esther |
Oliver |
| Before |
1 u + $55 |
3 u - $75 |
| Change |
- $55 |
+ $75 |
| After |
1 u |
3 u |
Esther and Oliver had the same amount of money at first.
3 u - 75 = 1 u + 55
3 u - 1 u = 55 + 75
2 u = 130
1 u = 130 ÷ 2 = 65
Amount that Esther had at first
= 1 u + 55
= 65 + 55
= $120
Answer(s): $120
