Bobby had $4.20 less than Asher. After Bobby gave $2.30 to Asher, Asher would have thrice as much money as Bobby. How much money had Asher at first?

Asher |
Bobby |
| Before |
3 u - $2.30 |
1 u + $2.30 |
| Change |
+ $2.30 |
- $2.30 |
| After |
3 u |
1 u |
Bobby had $4.20 less than Asher. If another $4.20 was given to Bobby, Asher and Bobby would have the same amount at first.
3 u - 2.30 = 1 u + 2.30 + 4.20
3 u - 1 u = 2.30 + 4.20 + 2.30
2 u = 8.80
1 u = 8.80 ÷ 2 = 4.40
Amount that Asher had at first
= 3 u - 2.30
= 3 x 4.40 + 2.30
= 13.20 + 2.30
= $15.50
Answer(s): $15.50
