56 as much money left as Raeann. How much money did the two girls have at first?

Raeann |
Erika |
| Before |
19 u + 120 |
29 u + 100 |
| Change |
- 19 u |
- 29 u |
| After |
$120 |
$100 |
Amount that Erika had left
=
56 x 120
= $100
The amount that Raeann and Erika had at first is the same.
29 u + 100 = 19 u + 120
29 u - 19 u = 120 - 100
10 u = 20
1 u = 20 ÷ 10 = 2
Amount that Raeann had at first
= 19 u + 120
= 19 x 2 + 120
= 38 + 120
= $158
Total amount that both girls had at first
= 2 x 158
= $316
Answer(s): $316
