59 as much money left as Lynn. How much money did the two girls have at first?

Lynn |
Lucy |
| Before |
3 u + 108 |
6 u + 60 |
| Change |
- 3 u |
- 6 u |
| After |
$108 |
$60 |
Amount that Lucy had left
=
59 x 108
= $60
The amount that Lynn and Lucy had at first is the same.
6 u + 60 = 3 u + 108
6 u - 3 u = 108 - 60
3 u = 48
1 u = 48 ÷ 3 = 16
Amount that Lynn had at first
= 3 u + 108
= 3 x 16 + 108
= 48 + 108
= $156
Total amount that both girls had at first
= 2 x 156
= $312
Answer(s): $312
