23 of his money, Will had $80.30 more than Carl. How much money did Will have at first?

Will |
Carl |
More |
| Before |
3 u + $55.90 |
3 u |
$55.90 |
| Change |
|
- 2 u |
|
| After |
3 u + $55.90 |
1 u |
2 u + $55.90 |
Will had $80.30 more than Carl in the end.
3 u + 55.90 - 1 u = 80.30
2 u + 55.90 = 80.30
2 u = 80.30 - 55.90
2 u = 24.40
1 u = 24.40 ÷ 2 = 12.20
Amount that Will had at first
= 3 u + 55.90
= 3 x 12.20 + 55.90
= 36.60 + 55.90
= $92.50
Answer(s): $92.50
