710 as much money left as Julie. How much money did the two girls have at first?

Julie |
Jen |
| Before |
6 u + 80 |
12 u + 56 |
| Change |
- 6 u |
- 12 u |
| After |
$80 |
$56 |
Amount that Jen had left
=
710 x 80
= $56
The amount that Julie and Jen had at first is the same.
12 u + 56 = 6 u + 80
12 u - 6 u = 80 - 56
6 u = 24
1 u = 24 ÷ 6 = 4
Amount that Julie had at first
= 6 u + 80
= 6 x 4 + 80
= 24 + 80
= $104
Total amount that both girls had at first
= 2 x 104
= $208
Answer(s): $208
