- 4 u |

After |
7 u + $44.70 |
3 u |
4 u + $44.70 |
Simon had $70.30 more than Glen in the end.
7 u + 44.70 - 3 u = 70.30
4 u + 44.70 = 70.30
4 u = 70.30 - 44.70
4 u = 25.60
1 u = 25.60 ÷ 4 = 6.40
Amount that Simon had at first
= 7 u + 44.70
= 7 x 6.40 + 44.70
= 44.80 + 44.70
= $89.50
Answer(s): $89.50
