Harry had $3.10 less than Seth. After Harry gave $2.50 to Seth, Seth would have four times as much money as Harry. How much money had Seth at first?
| |
Seth |
Harry |
| Before |
4 u - $2.50 |
1 u + $2.50 |
| Change |
+ $2.50 |
- $2.50 |
| After |
4 u |
1 u |
Harry had $3.10 less than Seth. If another $3.10 was given to Harry, Seth and Harry would have the same amount at first.
4 u - 2.50 = 1 u + 2.50 + 3.10
4 u - 1 u = 2.50 + 3.10 + 2.50
3 u = 8.10
1 u = 8.10 ÷ 3 = 2.70
Amount that Seth had at first
= 4 u - 2.50
= 4 x 2.70 + 2.50
= 10.80 + 2.50
= $13.30
Answer(s): $13.30
