Seth had $34.80 more than Ben. After Ben had spent
35 of his money, Seth had $80.70 more than Ben. How much money did Seth have at first?

Seth |
Ben |
More |
| Before |
5 u + $34.80 |
5 u |
$34.80 |
| Change |
|
- 3 u |
|
| After |
5 u + $34.80 |
2 u |
3 u + $34.80 |
Seth had $80.70 more than Ben in the end.
5 u + 34.80 - 2 u = 80.70
3 u + 34.80 = 80.70
3 u = 80.70 - 34.80
3 u = 45.90
1 u = 45.90 ÷ 3 = 15.30
Amount that Seth had at first
= 5 u + 34.80
= 5 x 15.30 + 34.80
= 76.50 + 34.80
= $111.30
Answer(s): $111.30
