Cody had $13.40 less than Cole. After Cody gave $3.10 to Cole, Cole would have five times as much money as Cody. How much money had Cole at first?
| |
Cole |
Cody |
| Before |
5 u - $3.10 |
1 u + $3.10 |
| Change |
+ $3.10 |
- $3.10 |
| After |
5 u |
1 u |
Cody had $13.40 less than Cole. If another $13.40 was given to Cody, Cole and Cody would have the same amount at first.
5 u - 3.10 = 1 u + 3.10 + 13.40
5 u - 1 u = 3.10 + 13.40 + 3.10
4 u = 19.60
1 u = 19.60 ÷ 4 = 4.90
Amount that Cole had at first
= 5 u - 3.10
= 5 x 4.90 + 3.10
= 24.50 + 3.10
= $27.60
Answer(s): $27.60
