| Before |
9 u + $42.20 |
9 u |
$42.20 |
| Change |
|
- 4 u |
|
| After |
9 u + $42.20 |
5 u |
4 u + $42.20 |
George had $57.40 more than Fabian in the end.
9 u + 42.20 - 5 u = 57.40
4 u + 42.20 = 57.40
4 u = 57.40 - 42.20
4 u = 15.20
1 u = 15.20 ÷ 4 = 3.80
Amount that George had at first
= 9 u + 42.20
= 9 x 3.80 + 42.20
= 34.20 + 42.20
= $76.40
Answer(s): $76.40
