Glen had $8.10 less than Lee. After Glen gave $2.40 to Lee, Lee would have four times as much money as Glen. How much money had Lee at first?

Lee |
Glen |
| Before |
4 u - $2.40 |
1 u + $2.40 |
| Change |
+ $2.40 |
- $2.40 |
| After |
4 u |
1 u |
Glen had $8.10 less than Lee. If another $8.10 was given to Glen, Lee and Glen would have the same amount at first.
4 u - 2.40 = 1 u + 2.40 + 8.10
4 u - 1 u = 2.40 + 8.10 + 2.40
3 u = 12.90
1 u = 12.90 ÷ 3 = 4.30
Amount that Lee had at first
= 4 u - 2.40
= 4 x 4.30 + 2.40
= 17.20 + 2.40
= $19.60
Answer(s): $19.60
