58 as much money left as Jen. How much money did the two girls have at first?

Jen |
Shannon |
| Before |
5 u + 80 |
8 u + 50 |
| Change |
- 5 u |
- 8 u |
| After |
$80 |
$50 |
Amount that Shannon had left
=
58 x 80
= $50
The amount that Jen and Shannon had at first is the same.
8 u + 50 = 5 u + 80
8 u - 5 u = 80 - 50
3 u = 30
1 u = 30 ÷ 3 = 10
Amount that Jen had at first
= 5 u + 80
= 5 x 10 + 80
= 50 + 80
= $130
Total amount that both girls had at first
= 2 x 130
= $260
Answer(s): $260
