13 as much money as Aubrey at first. After Lilian received $215 and Aubrey received $89, both of them had the same amount of money. How much did Aubrey have at first?

Lilian |
Aubrey |
| Before |
1 u |
3 u |
| Change |
+ 215 |
+ 89 |
| After |
1 u + 215 |
3 u + 89 |
The amount that Lilian and Aubrey had in the end is the same.
1 u + 215 = 3 u + 89
3 u - 1 u = 215 - 89 = 126
2 u = 126
1 u = 126 ÷ 2 = 63
Amount that Aubrey had at first
= 3 u
= 3 x 63
= $189
Answer(s): $189
