Cody had $11.80 less than Warren. After Cody gave $1.30 to Warren, Warren would have four times as much money as Cody. How much money had Warren at first?
| |
Warren |
Cody |
| Before |
4 u - $1.30 |
1 u + $1.30 |
| Change |
+ $1.30 |
- $1.30 |
| After |
4 u |
1 u |
Cody had $11.80 less than Warren. If another $11.80 was given to Cody, Warren and Cody would have the same amount at first.
4 u - 1.30 = 1 u + 1.30 + 11.80
4 u - 1 u = 1.30 + 11.80 + 1.30
3 u = 14.40
1 u = 14.40 ÷ 3 = 4.80
Amount that Warren had at first
= 4 u - 1.30
= 4 x 4.80 + 1.30
= 19.20 + 1.30
= $20.50
Answer(s): $20.50
