Henry had $5.70 less than Peter. After Henry gave $2.70 to Peter, Peter would have four times as much money as Henry. How much money had Peter at first?
| |
Peter |
Henry |
| Before |
4 u - $2.70 |
1 u + $2.70 |
| Change |
+ $2.70 |
- $2.70 |
| After |
4 u |
1 u |
Henry had $5.70 less than Peter. If another $5.70 was given to Henry, Peter and Henry would have the same amount at first.
4 u - 2.70 = 1 u + 2.70 + 5.70
4 u - 1 u = 2.70 + 5.70 + 2.70
3 u = 11.10
1 u = 11.10 ÷ 3 = 3.70
Amount that Peter had at first
= 4 u - 2.70
= 4 x 3.70 + 2.70
= 14.80 + 2.70
= $17.50
Answer(s): $17.50
