Nathan had
13 as much money as Ellie at first. After Nathan received $164 and Ellie received $72, both of them had the same amount of money. How much did Ellie have at first?

Nathan |
Ellie |
| Before |
1 u |
3 u |
| Change |
+ 164 |
+ 72 |
| After |
1 u + 164 |
3 u + 72 |
The amount that Nathan and Ellie had in the end is the same.
1 u + 164 = 3 u + 72
3 u - 1 u = 164 - 72 = 92
2 u = 92
1 u = 92 ÷ 2 = 46
Amount that Ellie had at first
= 3 u
= 3 x 46
= $138
Answer(s): $138
