Rael had
13 as much money as Layla at first. After Rael received $290 and Layla received $72, both of them had the same amount of money. How much did Layla have at first?

Rael |
Layla |
| Before |
1 u |
3 u |
| Change |
+ 290 |
+ 72 |
| After |
1 u + 290 |
3 u + 72 |
The amount that Rael and Layla had in the end is the same.
1 u + 290 = 3 u + 72
3 u - 1 u = 290 - 72 = 218
2 u = 218
1 u = 218 ÷ 2 = 109
Amount that Layla had at first
= 3 u
= 3 x 109
= $327
Answer(s): $327
