Fred had $8.60 less than Jeremy. After Fred gave $2.30 to Jeremy, Jeremy would have four times as much money as Fred. How much money had Jeremy at first?
| |
Jeremy |
Fred |
| Before |
4 u - $2.30 |
1 u + $2.30 |
| Change |
+ $2.30 |
- $2.30 |
| After |
4 u |
1 u |
Fred had $8.60 less than Jeremy. If another $8.60 was given to Fred, Jeremy and Fred would have the same amount at first.
4 u - 2.30 = 1 u + 2.30 + 8.60
4 u - 1 u = 2.30 + 8.60 + 2.30
3 u = 13.20
1 u = 13.20 ÷ 3 = 4.40
Amount that Jeremy had at first
= 4 u - 2.30
= 4 x 4.40 + 2.30
= 17.60 + 2.30
= $19.90
Answer(s): $19.90
