| Before |
9 u + $53.30 |
9 u |
$53.30 |
| Change |
|
- 2 u |
|
| After |
9 u + $53.30 |
7 u |
2 u + $53.30 |
Glen had $60.70 more than Ben in the end.
9 u + 53.30 - 7 u = 60.70
2 u + 53.30 = 60.70
2 u = 60.70 - 53.30
2 u = 7.40
1 u = 7.40 ÷ 2 = 3.70
Amount that Glen had at first
= 9 u + 53.30
= 9 x 3.70 + 53.30
= 33.30 + 53.30
= $86.60
Answer(s): $86.60
