Gabriel had $6.80 less than Ian. After Gabriel gave $1.40 to Ian, Ian would have thrice as much money as Gabriel. How much money had Ian at first?
| |
Ian |
Gabriel |
| Before |
3 u - $1.40 |
1 u + $1.40 |
| Change |
+ $1.40 |
- $1.40 |
| After |
3 u |
1 u |
Gabriel had $6.80 less than Ian. If another $6.80 was given to Gabriel, Ian and Gabriel would have the same amount at first.
3 u - 1.40 = 1 u + 1.40 + 6.80
3 u - 1 u = 1.40 + 6.80 + 1.40
2 u = 9.60
1 u = 9.60 ÷ 2 = 4.80
Amount that Ian had at first
= 3 u - 1.40
= 3 x 4.80 + 1.40
= 14.40 + 1.40
= $15.80
Answer(s): $15.80
