Jenson had $2.40 less than Andy. After Jenson gave $3.70 to Andy, Andy would have thrice as much money as Jenson. How much money had Andy at first?

Andy |
Jenson |
| Before |
3 u - $3.70 |
1 u + $3.70 |
| Change |
+ $3.70 |
- $3.70 |
| After |
3 u |
1 u |
Jenson had $2.40 less than Andy. If another $2.40 was given to Jenson, Andy and Jenson would have the same amount at first.
3 u - 3.70 = 1 u + 3.70 + 2.40
3 u - 1 u = 3.70 + 2.40 + 3.70
2 u = 9.80
1 u = 9.80 ÷ 2 = 4.90
Amount that Andy had at first
= 3 u - 3.70
= 3 x 4.90 + 3.70
= 14.70 + 3.70
= $18.40
Answer(s): $18.40
