Linda and Peter had the same amount of money at first. After Linda spent $9 on a wallet and Peter received $61 from his father, Peter had 3 times as much as money as Linda. How much money did Linda have at first?
| |
Linda |
Peter |
| Before |
1 u + $9 |
3 u - $61 |
| Change |
- $9 |
+ $61 |
| After |
1 u |
3 u |
Linda and Peter had the same amount of money at first.
3 u - 61 = 1 u + 9
3 u - 1 u = 9 + 61
2 u = 70
1 u = 70 ÷ 2 = 35
Amount that Linda had at first
= 1 u + 9
= 35 + 9
= $44
Answer(s): $44
