17 as much money left as Victoria. How much money did the two girls have at first?

Victoria |
Mary |
| Before |
8 u + 84 |
11 u + 12 |
| Change |
- 8 u |
- 11 u |
| After |
$84 |
$12 |
Amount that Mary had left
=
17 x 84
= $12
The amount that Victoria and Mary had at first is the same.
11 u + 12 = 8 u + 84
11 u - 8 u = 84 - 12
3 u = 72
1 u = 72 ÷ 3 = 24
Amount that Victoria had at first
= 8 u + 84
= 8 x 24 + 84
= 192 + 84
= $276
Total amount that both girls had at first
= 2 x 276
= $552
Answer(s): $552
