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

Fanny |
Gillian |
| Before |
19 u + 80 |
23 u + 72 |
| Change |
- 19 u |
- 23 u |
| After |
$80 |
$72 |
Amount that Gillian had left
=
910 x 80
= $72
The amount that Fanny and Gillian had at first is the same.
23 u + 72 = 19 u + 80
23 u - 19 u = 80 - 72
4 u = 8
1 u = 8 ÷ 4 = 2
Amount that Fanny had at first
= 19 u + 80
= 19 x 2 + 80
= 38 + 80
= $118
Total amount that both girls had at first
= 2 x 118
= $236
Answer(s): $236
