George had $34 more than Risa. After Risa spent
23 of her money, George had five times as much money as Risa. How much money did George have at first?
| |
George |
Risa |
| Before |
5 u |
3 u |
| Change |
|
- 2 u |
| After |
5 u |
1 u |
Amount that George had in the end
= 5 x 1 u
= 5 u
If Risa had another $34 at first, the amounts that George and Risa each had at first will be the same.
5 u = 3 u + 34
5 u - 3 u = 34
2 u = 34
1 u = 34 ÷ 2 = 17
Amount George had at first
= 5 u
= 5 x 17
= $85
Answer(s): $85
