Brandon |
| Before |
3 u - $1.10 |
1 u + $1.10 |

| After |
3 u |
1 u |
Brandon had $6.60 less than Cody. If another $6.60 was given to Brandon, Cody and Brandon would have the same amount at first.
3 u - 1.10 = 1 u + 1.10 + 6.60
3 u - 1 u = 1.10 + 6.60 + 1.10
2 u = 8.80
1 u = 8.80 ÷ 2 = 4.40
Amount that Cody had at first
= 3 u - 1.10
= 3 x 4.40 + 1.10
= 13.20 + 1.10
= $14.30
Answer(s): $14.30
