Oscar had $50 more than Jane. After Jane spent
23 of her money, Oscar had five times as much money as Jane. How much money did Oscar have at first?
| |
Oscar |
Jane |
| Before |
5 u |
3 u |
| Change |
|
- 2 u |
| After |
5 u |
1 u |
Amount that Oscar had in the end
= 5 x 1 u
= 5 u
If Jane had another $50 at first, the amounts that Oscar and Jane each had at first will be the same.
5 u = 3 u + 50
5 u - 3 u = 50
2 u = 50
1 u = 50 ÷ 2 = 25
Amount Oscar had at first
= 5 u
= 5 x 25
= $125
Answer(s): $125
