| Before |
14 u + 99 |
17 u + 33 |
| Change |
- 14 u |
- 17 u |
| After |
$99 |
$33 |
Amount that Vanessa had left
=
13 x 99
= $33
The amount that Elyse and Vanessa had at first is the same.
17 u + 33 = 14 u + 99
17 u - 14 u = 99 - 33
3 u = 66
1 u = 66 ÷ 3 = 22
Amount that Elyse had at first
= 14 u + 99
= 14 x 22 + 99
= 308 + 99
= $407
Total amount that both girls had at first
= 2 x 407
= $814
Answer(s): $814
