Simon had $39.90 more than Fabian. After Fabian had spent
23 of his money, Simon had $59.50 more than Fabian. How much money did Simon have at first?

Simon |
Fabian |
More |
| Before |
3 u + $39.90 |
3 u |
$39.90 |
| Change |
|
- 2 u |
|
| After |
3 u + $39.90 |
1 u |
2 u + $39.90 |
Simon had $59.50 more than Fabian in the end.
3 u + 39.90 - 1 u = 59.50
2 u + 39.90 = 59.50
2 u = 59.50 - 39.90
2 u = 19.60
1 u = 19.60 ÷ 2 = 9.80
Amount that Simon had at first
= 3 u + 39.90
= 3 x 9.80 + 39.90
= 29.40 + 39.90
= $69.30
Answer(s): $69.30
