| Before |
8 u + 88 |
12 u + 72 |
| Change |
- 8 u |
- 12 u |
| After |
$88 |
$72 |
Amount that Nora had left
=
911 x 88
= $72
The amount that Dana and Nora had at first is the same.
12 u + 72 = 8 u + 88
12 u - 8 u = 88 - 72
4 u = 16
1 u = 16 ÷ 4 = 4
Amount that Dana had at first
= 8 u + 88
= 8 x 4 + 88
= 32 + 88
= $120
Total amount that both girls had at first
= 2 x 120
= $240
Answer(s): $240
