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

Gwen |
Shannon |
| Before |
5 u + 108 |
14 u + 90 |
| Change |
- 5 u |
- 14 u |
| After |
$108 |
$90 |
Amount that Shannon had left
=
56 x 108
= $90
The amount that Gwen and Shannon had at first is the same.
14 u + 90 = 5 u + 108
14 u - 5 u = 108 - 90
9 u = 18
1 u = 18 ÷ 9 = 2
Amount that Gwen had at first
= 5 u + 108
= 5 x 2 + 108
= 10 + 108
= $118
Total amount that both girls had at first
= 2 x 118
= $236
Answer(s): $236
