Victoria had
13 as much money as Christian at first. After Victoria received $187 and Christian received $87, both of them had the same amount of money. How much did Christian have at first?

Victoria |
Christian |
| Before |
1 u |
3 u |
| Change |
+ 187 |
+ 87 |
| After |
1 u + 187 |
3 u + 87 |
The amount that Victoria and Christian had in the end is the same.
1 u + 187 = 3 u + 87
3 u - 1 u = 187 - 87 = 100
2 u = 100
1 u = 100 ÷ 2 = 50
Amount that Christian had at first
= 3 u
= 3 x 50
= $150
Answer(s): $150
