110 as much money left as Marion. How much money did the two girls have at first?

Marion |
Gabby |
| Before |
14 u + 80 |
18 u + 8 |
| Change |
- 14 u |
- 18 u |
| After |
$80 |
$8 |
Amount that Gabby had left
=
110 x 80
= $8
The amount that Marion and Gabby had at first is the same.
18 u + 8 = 14 u + 80
18 u - 14 u = 80 - 8
4 u = 72
1 u = 72 ÷ 4 = 18
Amount that Marion had at first
= 14 u + 80
= 14 x 18 + 80
= 252 + 80
= $332
Total amount that both girls had at first
= 2 x 332
= $664
Answer(s): $664
