Ella had
13 as much money as Grace at first. After Ella received $317 and Grace received $73, both of them had the same amount of money. How much did Grace have at first?

Ella |
Grace |
| Before |
1 u |
3 u |
| Change |
+ 317 |
+ 73 |
| After |
1 u + 317 |
3 u + 73 |
The amount that Ella and Grace had in the end is the same.
1 u + 317 = 3 u + 73
3 u - 1 u = 317 - 73 = 244
2 u = 244
1 u = 244 ÷ 2 = 122
Amount that Grace had at first
= 3 u
= 3 x 122
= $366
Answer(s): $366
