14 as much money left as Fanny. How much money did the two girls have at first?

Gillian |
| Before |
8 u + 108 |
11 u + 27 |
| Change |
- 8 u |
- 11 u |
| After |
$108 |
$27 |
Amount that Gillian had left
=
14 x 108
= $27
The amount that Fanny and Gillian had at first is the same.
11 u + 27 = 8 u + 108
11 u - 8 u = 108 - 27
3 u = 81
1 u = 81 ÷ 3 = 27
Amount that Fanny had at first
= 8 u + 108
= 8 x 27 + 108
= 216 + 108
= $324
Total amount that both girls had at first
= 2 x 324
= $648
Answer(s): $648
