Reggie had $50 more than Gwen. After Gwen spent
13 of her money, Reggie had four times as much money as Gwen. How much money did Reggie have at first?
| |
Reggie |
Gwen |
| Before |
8 u |
3 u |
| Change |
|
- 1 u |
| After |
8 u |
2 u |
Amount that Reggie had in the end
= 4 x 2 u
= 8 u
If Gwen had another $50 at first, the amounts that Reggie and Gwen each had at first will be the same.
8 u = 3 u + 50
8 u - 3 u = 50
5 u = 50
1 u = 50 ÷ 5 = 10
Amount Reggie had at first
= 8 u
= 8 x 10
= $80
Answer(s): $80
