Sean had $60 more than Rachel. After Rachel spent
25 of her money, Sean had thrice as much money as Rachel. How much money did Sean have at first?
| |
Sean |
Rachel |
| Before |
9 u |
5 u |
| Change |
|
- 2 u |
| After |
9 u |
3 u |
Amount that Sean had in the end
= 3 x 3 u
= 9 u
If Rachel had another $60 at first, the amounts that Sean and Rachel each had at first will be the same.
9 u = 5 u + 60
9 u - 5 u = 60
4 u = 60
1 u = 60 ÷ 4 = 15
Amount Sean had at first
= 9 u
= 9 x 15
= $135
Answer(s): $135
