Luis had $8.80 less than Cody. After Luis gave $3.80 to Cody, Cody would have five times as much money as Luis. How much money had Cody at first?
| |
Cody |
Luis |
| Before |
5 u - $3.80 |
1 u + $3.80 |
| Change |
+ $3.80 |
- $3.80 |
| After |
5 u |
1 u |
Luis had $8.80 less than Cody. If another $8.80 was given to Luis, Cody and Luis would have the same amount at first.
5 u - 3.80 = 1 u + 3.80 + 8.80
5 u - 1 u = 3.80 + 8.80 + 3.80
4 u = 16.40
1 u = 16.40 ÷ 4 = 4.10
Amount that Cody had at first
= 5 u - 3.80
= 5 x 4.10 + 3.80
= 20.50 + 3.80
= $24.30
Answer(s): $24.30
