Emily had
13 as much money as Lucas at first. After Emily received $250 and Lucas received $90, both of them had the same amount of money. How much did Lucas have at first?

Emily |
Lucas |
| Before |
1 u |
3 u |
| Change |
+ 250 |
+ 90 |
| After |
1 u + 250 |
3 u + 90 |
The amount that Emily and Lucas had in the end is the same.
1 u + 250 = 3 u + 90
3 u - 1 u = 250 - 90 = 160
2 u = 160
1 u = 160 ÷ 2 = 80
Amount that Lucas had at first
= 3 u
= 3 x 80
= $240
Answer(s): $240
