67 as much money left as Ivory. How much money did the two girls have at first?

Ivory |
Yoko |
| Before |
5 u + 84 |
11 u + 72 |
| Change |
- 5 u |
- 11 u |
| After |
$84 |
$72 |
Amount that Yoko had left
=
67 x 84
= $72
The amount that Ivory and Yoko had at first is the same.
11 u + 72 = 5 u + 84
11 u - 5 u = 84 - 72
6 u = 12
1 u = 12 ÷ 6 = 2
Amount that Ivory had at first
= 5 u + 84
= 5 x 2 + 84
= 10 + 84
= $94
Total amount that both girls had at first
= 2 x 94
= $188
Answer(s): $188
