Cathy and Andy had the same amount of money at first. After Cathy spent $55 on a wallet and Andy received $25 from his aunt, Andy had 5 times as much as money as Cathy. How much money did Cathy have at first?

Cathy |
Andy |
| Before |
1 u + $55 |
5 u - $25 |
| Change |
- $55 |
+ $25 |
| After |
1 u |
5 u |
Cathy and Andy had the same amount of money at first.
5 u - 25 = 1 u + 55
5 u - 1 u = 55 + 25
4 u = 80
1 u = 80 ÷ 4 = 20
Amount that Cathy had at first
= 1 u + 55
= 20 + 55
= $75
Answer(s): $75
