17 as much money left as Eva. How much money did the two girls have at first?

Eva |
Lynn |
| Before |
8 u + 91 |
14 u + 13 |
| Change |
- 8 u |
- 14 u |
| After |
$91 |
$13 |
Amount that Lynn had left
=
17 x 91
= $13
The amount that Eva and Lynn had at first is the same.
14 u + 13 = 8 u + 91
14 u - 8 u = 91 - 13
6 u = 78
1 u = 78 ÷ 6 = 13
Amount that Eva had at first
= 8 u + 91
= 8 x 13 + 91
= 104 + 91
= $195
Total amount that both girls had at first
= 2 x 195
= $390
Answer(s): $390
