Grace had
13 as much money as Aubrey at first. After Grace received $276 and Aubrey received $78, both of them had the same amount of money. How much did Aubrey have at first?

Grace |
Aubrey |
| Before |
1 u |
3 u |
| Change |
+ 276 |
+ 78 |
| After |
1 u + 276 |
3 u + 78 |
The amount that Grace and Aubrey had in the end is the same.
1 u + 276 = 3 u + 78
3 u - 1 u = 276 - 78 = 198
2 u = 198
1 u = 198 ÷ 2 = 99
Amount that Aubrey had at first
= 3 u
= 3 x 99
= $297
Answer(s): $297
