- 3 u |

| After |
4 u + $88.80 |
1 u |
3 u + $88.80 |
George had $142.50 more than Oscar in the end.
4 u + 88.80 - 1 u = 142.50
3 u + 88.80 = 142.50
3 u = 142.50 - 88.80
3 u = 53.70
1 u = 53.70 ÷ 3 = 17.90
Amount that George had at first
= 4 u + 88.80
= 4 x 17.90 + 88.80
= 71.60 + 88.80
= $160.40
Answer(s): $160.40
