Jeremy had $50 more than Betty. After Betty spent
25 of her money, Jeremy had five times as much money as Betty. How much money did Jeremy have at first?
| |
Jeremy |
Betty |
| Before |
15 u |
5 u |
| Change |
|
- 2 u |
| After |
15 u |
3 u |
Amount that Jeremy had in the end
= 5 x 3 u
= 15 u
If Betty had another $50 at first, the amounts that Jeremy and Betty each had at first will be the same.
15 u = 5 u + 50
15 u - 5 u = 50
10 u = 50
1 u = 50 ÷ 10 = 5
Amount Jeremy had at first
= 15 u
= 15 x 5
= $75
Answer(s): $75
