34 as much money left as Irene. How much money did the two girls have at first?

Sabrina |
| Before |
4 u + 96 |
10 u + 72 |
| Change |
- 4 u |
- 10 u |
| After |
$96 |
$72 |
Amount that Sabrina had left
=
34 x 96
= $72
The amount that Irene and Sabrina had at first is the same.
10 u + 72 = 4 u + 96
10 u - 4 u = 96 - 72
6 u = 24
1 u = 24 ÷ 6 = 4
Amount that Irene had at first
= 4 u + 96
= 4 x 4 + 96
= 16 + 96
= $112
Total amount that both girls had at first
= 2 x 112
= $224
Answer(s): $224
