23 as much money left as Jane. How much money did the two girls have at first?

Jane |
Kylie |
| Before |
5 u + 108 |
8 u + 72 |
| Change |
- 5 u |
- 8 u |
| After |
$108 |
$72 |
Amount that Kylie had left
=
23 x 108
= $72
The amount that Jane and Kylie had at first is the same.
8 u + 72 = 5 u + 108
8 u - 5 u = 108 - 72
3 u = 36
1 u = 36 ÷ 3 = 12
Amount that Jane had at first
= 5 u + 108
= 5 x 12 + 108
= 60 + 108
= $168
Total amount that both girls had at first
= 2 x 168
= $336
Answer(s): $336
