Claire had
14 as much money as Christian at first. After Claire received $270 and Christian received $90, both of them had the same amount of money. How much did Christian have at first?

Claire |
Christian |
| Before |
1 u |
4 u |
| Change |
+ 270 |
+ 90 |
| After |
1 u + 270 |
4 u + 90 |
The amount that Claire and Christian had in the end is the same.
1 u + 270 = 4 u + 90
4 u - 1 u = 270 - 90 = 180
3 u = 180
1 u = 180 ÷ 3 = 60
Amount that Christian had at first
= 4 u
= 4 x 60
= $240
Answer(s): $240
