35 as much money left as Hazel. How much money did the two girls have at first?

Tammy |
| Before |
11 u + 120 |
15 u + 72 |
| Change |
- 11 u |
- 15 u |
| After |
$120 |
$72 |
Amount that Tammy had left
=
35 x 120
= $72
The amount that Hazel and Tammy had at first is the same.
15 u + 72 = 11 u + 120
15 u - 11 u = 120 - 72
4 u = 48
1 u = 48 ÷ 4 = 12
Amount that Hazel had at first
= 11 u + 120
= 11 x 12 + 120
= 132 + 120
= $252
Total amount that both girls had at first
= 2 x 252
= $504
Answer(s): $504
