34 of his money, Tom had $89.70 more than Vaidev. How much money did Tom have at first?

Tom |
Vaidev |
More |
| Before |
4 u + $71.10 |
4 u |
$71.10 |
| Change |
|
- 3 u |
|
| After |
4 u + $71.10 |
1 u |
3 u + $71.10 |
Tom had $89.70 more than Vaidev in the end.
4 u + 71.10 - 1 u = 89.70
3 u + 71.10 = 89.70
3 u = 89.70 - 71.10
3 u = 18.60
1 u = 18.60 ÷ 3 = 6.20
Amount that Tom had at first
= 4 u + 71.10
= 4 x 6.20 + 71.10
= 24.80 + 71.10
= $95.90
Answer(s): $95.90
