Howard had $4.70 less than Cody. After Howard gave $2.60 to Cody, Cody would have four times as much money as Howard. How much money had Cody at first?

Cody |
Howard |
| Before |
4 u - $2.60 |
1 u + $2.60 |
| Change |
+ $2.60 |

| After |
4 u |
1 u |
Howard had $4.70 less than Cody. If another $4.70 was given to Howard, Cody and Howard would have the same amount at first.
4 u - 2.60 = 1 u + 2.60 + 4.70
4 u - 1 u = 2.60 + 4.70 + 2.60
3 u = 9.90
1 u = 9.90 ÷ 3 = 3.30
Amount that Cody had at first
= 4 u - 2.60
= 4 x 3.30 + 2.60
= 13.20 + 2.60
= $15.80
Answer(s): $15.80
