Will had $5.10 less than Cody. After Will gave $1.80 to Cody, Cody would have four times as much money as Will. How much money had Cody at first?
| |
Cody |
Will |
| Before |
4 u - $1.80 |
1 u + $1.80 |
| Change |
+ $1.80 |
- $1.80 |
| After |
4 u |
1 u |
Will had $5.10 less than Cody. If another $5.10 was given to Will, Cody and Will would have the same amount at first.
4 u - 1.80 = 1 u + 1.80 + 5.10
4 u - 1 u = 1.80 + 5.10 + 1.80
3 u = 8.70
1 u = 8.70 ÷ 3 = 2.90
Amount that Cody had at first
= 4 u - 1.80
= 4 x 2.90 + 1.80
= 11.60 + 1.80
= $13.40
Answer(s): $13.40
