Rebecca had
13 as much money as Lucas at first. After Rebecca received $326 and Lucas received $66, both of them had the same amount of money. How much did Lucas have at first?

Rebecca |
Lucas |
Before |
1 u |
3 u |
Change |
+ 326 |
+ 66 |
After |
1 u + 326 |
3 u + 66 |
The amount that Rebecca and Lucas had in the end is the same.
1 u + 326 = 3 u + 66
3 u - 1 u = 326 - 66 = 260
2 u = 260
1 u = 260 ÷ 2 = 130
Amount that Lucas had at first
= 3 u
= 3 x 130
= $390
Answer(s): $390
