Eric had $16.20 less than Seth. After Eric gave $1.70 to Seth, Seth would have five times as much money as Eric. How much money had Seth at first?

Seth |
Eric |
| Before |
5 u - $1.70 |
1 u + $1.70 |
| Change |
+ $1.70 |
- $1.70 |
| After |
5 u |
1 u |
Eric had $16.20 less than Seth. If another $16.20 was given to Eric, Seth and Eric would have the same amount at first.
5 u - 1.70 = 1 u + 1.70 + 16.20
5 u - 1 u = 1.70 + 16.20 + 1.70
4 u = 19.60
1 u = 19.60 ÷ 4 = 4.90
Amount that Seth had at first
= 5 u - 1.70
= 5 x 4.90 + 1.70
= 24.50 + 1.70
= $26.20
Answer(s): $26.20
