| Before |
16 u + 99 |
25 u + 18 |
| Change |
- 16 u |
- 25 u |
| After |
$99 |
$18 |
Amount that Kylie had left
=
211 x 99
= $18
The amount that Min and Kylie had at first is the same.
25 u + 18 = 16 u + 99
25 u - 16 u = 99 - 18
9 u = 81
1 u = 81 ÷ 9 = 9
Amount that Min had at first
= 16 u + 99
= 16 x 9 + 99
= 144 + 99
= $243
Total amount that both girls had at first
= 2 x 243
= $486
Answer(s): $486
