Gavin had
13 as much money as Dylan at first. After Gavin received $333 and Dylan received $99, both of them had the same amount of money. How much did Dylan have at first?

Gavin |
Dylan |
| Before |
1 u |
3 u |
| Change |
+ 333 |
+ 99 |
| After |
1 u + 333 |
3 u + 99 |
The amount that Gavin and Dylan had in the end is the same.
1 u + 333 = 3 u + 99
3 u - 1 u = 333 - 99 = 234
2 u = 234
1 u = 234 ÷ 2 = 117
Amount that Dylan had at first
= 3 u
= 3 x 117
= $351
Answer(s): $351
