Gabriel had $11.20 less than Tom. After Gabriel gave $1.60 to Tom, Tom would have four times as much money as Gabriel. How much money had Tom at first?
| |
Tom |
Gabriel |
| Before |
4 u - $1.60 |
1 u + $1.60 |
| Change |
+ $1.60 |
- $1.60 |
| After |
4 u |
1 u |
Gabriel had $11.20 less than Tom. If another $11.20 was given to Gabriel, Tom and Gabriel would have the same amount at first.
4 u - 1.60 = 1 u + 1.60 + 11.20
4 u - 1 u = 1.60 + 11.20 + 1.60
3 u = 14.40
1 u = 14.40 ÷ 3 = 4.80
Amount that Tom had at first
= 4 u - 1.60
= 4 x 4.80 + 1.60
= 19.20 + 1.60
= $20.80
Answer(s): $20.80
