Ben had $60 more than Linda. After Linda spent
13 of her money, Ben had thrice as much money as Linda. How much money did Ben have at first?
| |
Ben |
Linda |
| Before |
6 u |
3 u |
| Change |
|
- 1 u |
| After |
6 u |
2 u |
Amount that Ben had in the end
= 3 x 2 u
= 6 u
If Linda had another $60 at first, the amounts that Ben and Linda each had at first will be the same.
6 u = 3 u + 60
6 u - 3 u = 60
3 u = 60
1 u = 60 ÷ 3 = 20
Amount Ben had at first
= 6 u
= 6 x 20
= $120
Answer(s): $120
