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

Ivory |
| Before |
20 u + 98 |
27 u + 28 |
| Change |
- 20 u |
- 27 u |
| After |
$98 |
$28 |
Amount that Ivory had left
=
27 x 98
= $28
The amount that Julie and Ivory had at first is the same.
27 u + 28 = 20 u + 98
27 u - 20 u = 98 - 28
7 u = 70
1 u = 70 ÷ 7 = 10
Amount that Julie had at first
= 20 u + 98
= 20 x 10 + 98
= 200 + 98
= $298
Total amount that both girls had at first
= 2 x 298
= $596
Answer(s): $596
