| Before |
4 u - $2.20 |
1 u + $2.20 |

| After |
4 u |
1 u |
Liam had $5.50 less than Reggie. If another $5.50 was given to Liam, Reggie and Liam would have the same amount at first.
4 u - 2.20 = 1 u + 2.20 + 5.50
4 u - 1 u = 2.20 + 5.50 + 2.20
3 u = 9.90
1 u = 9.90 ÷ 3 = 3.30
Amount that Reggie had at first
= 4 u - 2.20
= 4 x 3.30 + 2.20
= 13.20 + 2.20
= $15.40
Answer(s): $15.40
