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

Tammy |
| Before |
19 u + 96 |
25 u + 48 |
| Change |
- 19 u |
- 25 u |
| After |
$96 |
$48 |
Amount that Tammy had left
=
12 x 96
= $48
The amount that Natalie and Tammy had at first is the same.
25 u + 48 = 19 u + 96
25 u - 19 u = 96 - 48
6 u = 48
1 u = 48 ÷ 6 = 8
Amount that Natalie had at first
= 19 u + 96
= 19 x 8 + 96
= 152 + 96
= $248
Total amount that both girls had at first
= 2 x 248
= $496
Answer(s): $496
