Samuel had
13 as much money as Ellie at first. After Samuel received $181 and Ellie received $61, both of them had the same amount of money. How much did Ellie have at first?

Samuel |
Ellie |
| Before |
1 u |
3 u |
| Change |
+ 181 |
+ 61 |
| After |
1 u + 181 |
3 u + 61 |
The amount that Samuel and Ellie had in the end is the same.
1 u + 181 = 3 u + 61
3 u - 1 u = 181 - 61 = 120
2 u = 120
1 u = 120 ÷ 2 = 60
Amount that Ellie had at first
= 3 u
= 3 x 60
= $180
Answer(s): $180
