Carl had $6.20 less than Glen. After Carl gave $2.70 to Glen, Glen would have five times as much money as Carl. How much money had Glen at first?

| Before |
5 u - $2.70 |
1 u + $2.70 |

| After |
5 u |
1 u |
Carl had $6.20 less than Glen. If another $6.20 was given to Carl, Glen and Carl would have the same amount at first.
5 u - 2.70 = 1 u + 2.70 + 6.20
5 u - 1 u = 2.70 + 6.20 + 2.70
4 u = 11.60
1 u = 11.60 ÷ 4 = 2.90
Amount that Glen had at first
= 5 u - 2.70
= 5 x 2.90 + 2.70
= 14.50 + 2.70
= $17.20
Answer(s): $17.20
