Layla had
13 as much money as Anthony at first. After Layla received $163 and Anthony received $73, both of them had the same amount of money. How much did Anthony have at first?

Layla |
Anthony |
| Before |
1 u |
3 u |
| Change |
+ 163 |
+ 73 |
| After |
1 u + 163 |
3 u + 73 |
The amount that Layla and Anthony had in the end is the same.
1 u + 163 = 3 u + 73
3 u - 1 u = 163 - 73 = 90
2 u = 90
1 u = 90 ÷ 2 = 45
Amount that Anthony had at first
= 3 u
= 3 x 45
= $135
Answer(s): $135
