Tommy had $3.40 less than Fabian. After Tommy gave $2.90 to Fabian, Fabian would have thrice as much money as Tommy. How much money had Fabian at first?
| |
Fabian |
Tommy |
| Before |
3 u - $2.90 |
1 u + $2.90 |
| Change |
+ $2.90 |
- $2.90 |
| After |
3 u |
1 u |
Tommy had $3.40 less than Fabian. If another $3.40 was given to Tommy, Fabian and Tommy would have the same amount at first.
3 u - 2.90 = 1 u + 2.90 + 3.40
3 u - 1 u = 2.90 + 3.40 + 2.90
2 u = 9.20
1 u = 9.20 ÷ 2 = 4.60
Amount that Fabian had at first
= 3 u - 2.90
= 3 x 4.60 + 2.90
= 13.80 + 2.90
= $16.70
Answer(s): $16.70
