Carl had $5.90 less than Ivan. After Carl gave $2.90 to Ivan, Ivan would have four times as much money as Carl. How much money had Ivan at first?
| |
Ivan |
Carl |
| Before |
4 u - $2.90 |
1 u + $2.90 |
| Change |
+ $2.90 |
- $2.90 |
| After |
4 u |
1 u |
Carl had $5.90 less than Ivan. If another $5.90 was given to Carl, Ivan and Carl would have the same amount at first.
4 u - 2.90 = 1 u + 2.90 + 5.90
4 u - 1 u = 2.90 + 5.90 + 2.90
3 u = 11.70
1 u = 11.70 ÷ 3 = 3.90
Amount that Ivan had at first
= 4 u - 2.90
= 4 x 3.90 + 2.90
= 15.60 + 2.90
= $18.50
Answer(s): $18.50
