13 as much money as Rael at first. After Julian received $152 and Rael received $72, both of them had the same amount of money. How much did Rael have at first?

Julian |
Rael |
| Before |
1 u |
3 u |
| Change |
+ 152 |
+ 72 |
| After |
1 u + 152 |
3 u + 72 |
The amount that Julian and Rael had in the end is the same.
1 u + 152 = 3 u + 72
3 u - 1 u = 152 - 72 = 80
2 u = 80
1 u = 80 ÷ 2 = 40
Amount that Rael had at first
= 3 u
= 3 x 40
= $120
Answer(s): $120
