12 as much money left as Kathy. How much money did the two girls have at first?

Kathy |
Roshel |
| Before |
19 u + 112 |
26 u + 56 |
| Change |
- 19 u |
- 26 u |
| After |
$112 |
$56 |
Amount that Roshel had left
=
12 x 112
= $56
The amount that Kathy and Roshel had at first is the same.
26 u + 56 = 19 u + 112
26 u - 19 u = 112 - 56
7 u = 56
1 u = 56 ÷ 7 = 8
Amount that Kathy had at first
= 19 u + 112
= 19 x 8 + 112
= 152 + 112
= $264
Total amount that both girls had at first
= 2 x 264
= $528
Answer(s): $528
