27 as much money left as Wendy. How much money did the two girls have at first?

Wendy |
Betty |
| Before |
15 u + 119 |
20 u + 34 |
| Change |
- 15 u |
- 20 u |
| After |
$119 |
$34 |
Amount that Betty had left
=
27 x 119
= $34
The amount that Wendy and Betty had at first is the same.
20 u + 34 = 15 u + 119
20 u - 15 u = 119 - 34
5 u = 85
1 u = 85 ÷ 5 = 17
Amount that Wendy had at first
= 15 u + 119
= 15 x 17 + 119
= 255 + 119
= $374
Total amount that both girls had at first
= 2 x 374
= $748
Answer(s): $748
