Daniel had $4.90 less than Andy. After Daniel gave $1.90 to Andy, Andy would have four times as much money as Daniel. How much money had Andy at first?
| |
Andy |
Daniel |
| Before |
4 u - $1.90 |
1 u + $1.90 |
| Change |
+ $1.90 |
- $1.90 |
| After |
4 u |
1 u |
Daniel had $4.90 less than Andy. If another $4.90 was given to Daniel, Andy and Daniel would have the same amount at first.
4 u - 1.90 = 1 u + 1.90 + 4.90
4 u - 1 u = 1.90 + 4.90 + 1.90
3 u = 8.70
1 u = 8.70 ÷ 3 = 2.90
Amount that Andy had at first
= 4 u - 1.90
= 4 x 2.90 + 1.90
= 11.60 + 1.90
= $13.50
Answer(s): $13.50
