| Before |
9 u + $67.50 |
9 u |
$67.50 |
| Change |
|
- 7 u |
|
| After |
9 u + $67.50 |
2 u |
7 u + $67.50 |
Reggie had $83.60 more than Vaidev in the end.
9 u + 67.50 - 2 u = 83.60
7 u + 67.50 = 83.60
7 u = 83.60 - 67.50
7 u = 16.10
1 u = 16.10 ÷ 7 = 2.30
Amount that Reggie had at first
= 9 u + 67.50
= 9 x 2.30 + 67.50
= 20.70 + 67.50
= $88.20
Answer(s): $88.20
