56 as much money left as Gwen. How much money did the two girls have at first?

Gwen |
Winnie |
| Before |
19 u + 108 |
22 u + 90 |
| Change |
- 19 u |
- 22 u |
| After |
$108 |
$90 |
Amount that Winnie had left
=
56 x 108
= $90
The amount that Gwen and Winnie had at first is the same.
22 u + 90 = 19 u + 108
22 u - 19 u = 108 - 90
3 u = 18
1 u = 18 ÷ 3 = 6
Amount that Gwen had at first
= 19 u + 108
= 19 x 6 + 108
= 114 + 108
= $222
Total amount that both girls had at first
= 2 x 222
= $444
Answer(s): $444
