Fabian |
More |
| Before |
3 u + $31.50 |
3 u |
$31.50 |
| Change |
|
- 2 u |
|
| After |
3 u + $31.50 |
1 u |
2 u + $31.50 |
Ahmad had $48.70 more than Fabian in the end.
3 u + 31.50 - 1 u = 48.70
2 u + 31.50 = 48.70
2 u = 48.70 - 31.50
2 u = 17.20
1 u = 17.20 ÷ 2 = 8.60
Amount that Ahmad had at first
= 3 u + 31.50
= 3 x 8.60 + 31.50
= 25.80 + 31.50
= $57.30
Answer(s): $57.30
