George |
| Before |
4 u - $3.50 |
1 u + $3.50 |

| After |
4 u |
1 u |
George had $4.40 less than Peter. If another $4.40 was given to George, Peter and George would have the same amount at first.
4 u - 3.50 = 1 u + 3.50 + 4.40
4 u - 1 u = 3.50 + 4.40 + 3.50
3 u = 11.40
1 u = 11.40 ÷ 3 = 3.80
Amount that Peter had at first
= 4 u - 3.50
= 4 x 3.80 + 3.50
= 15.20 + 3.50
= $18.70
Answer(s): $18.70
