67 of his money, Harry had $92.10 more than Justin. How much money did Harry have at first?

| Before |
7 u + $46.50 |
7 u |
$46.50 |
| Change |
|
- 6 u |
|
| After |
7 u + $46.50 |
1 u |
6 u + $46.50 |
Harry had $92.10 more than Justin in the end.
7 u + 46.50 - 1 u = 92.10
6 u + 46.50 = 92.10
6 u = 92.10 - 46.50
6 u = 45.60
1 u = 45.60 ÷ 6 = 7.60
Amount that Harry had at first
= 7 u + 46.50
= 7 x 7.60 + 46.50
= 53.20 + 46.50
= $99.70
Answer(s): $99.70
