37 of his money, Albert had $59.10 more than Seth. How much money did Albert have at first?

| Before |
7 u + $42.60 |
7 u |
$42.60 |
| Change |
|
- 3 u |
|
| After |
7 u + $42.60 |
4 u |
3 u + $42.60 |
Albert had $59.10 more than Seth in the end.
7 u + 42.60 - 4 u = 59.10
3 u + 42.60 = 59.10
3 u = 59.10 - 42.60
3 u = 16.50
1 u = 16.50 ÷ 3 = 5.50
Amount that Albert had at first
= 7 u + 42.60
= 7 x 5.50 + 42.60
= 38.50 + 42.60
= $81.10
Answer(s): $81.10
