111 as much money left as Nicole. How much money did the two girls have at first?

| Before |
17 u + 110 |
27 u + 10 |
| Change |
- 17 u |
- 27 u |
| After |
$110 |
$10 |
Amount that Esther had left
=
111 x 110
= $10
The amount that Nicole and Esther had at first is the same.
27 u + 10 = 17 u + 110
27 u - 17 u = 110 - 10
10 u = 100
1 u = 100 ÷ 10 = 10
Amount that Nicole had at first
= 17 u + 110
= 17 x 10 + 110
= 170 + 110
= $280
Total amount that both girls had at first
= 2 x 280
= $560
Answer(s): $560
