34 of his money, Tom had $69.30 more than Wesley. How much money did Tom have at first?

Tom |
Wesley |
More |
| Before |
4 u + $38.10 |
4 u |
$38.10 |
| Change |
|
- 3 u |
|
| After |
4 u + $38.10 |
1 u |
3 u + $38.10 |
Tom had $69.30 more than Wesley in the end.
4 u + 38.10 - 1 u = 69.30
3 u + 38.10 = 69.30
3 u = 69.30 - 38.10
3 u = 31.20
1 u = 31.20 ÷ 3 = 10.40
Amount that Tom had at first
= 4 u + 38.10
= 4 x 10.40 + 38.10
= 41.60 + 38.10
= $79.70
Answer(s): $79.70
