| Before |
14 u + 81 |
17 u + 36 |
| Change |
- 14 u |
- 17 u |
| After |
$81 |
$36 |
Amount that Fanny had left
=
49 x 81
= $36
The amount that Shannon and Fanny had at first is the same.
17 u + 36 = 14 u + 81
17 u - 14 u = 81 - 36
3 u = 45
1 u = 45 ÷ 3 = 15
Amount that Shannon had at first
= 14 u + 81
= 14 x 15 + 81
= 210 + 81
= $291
Total amount that both girls had at first
= 2 x 291
= $582
Answer(s): $582
