Change |
+ $36 |
- $10 |
|
After |
3 u + $36 |
5 u - $10 |
8 u + $26 |
Amount of money Cathy and Min has is the same in the end.
5 u - 10 = 3 u + 36
5 u - 3 u = 36 + 10
2 u = 46
1 u = 46 ÷ 2 = 23
Amount the girls have in the end
= 3 u + 36 + 5 u - 10
= 8 u + 26
= 8 x 23 + 26
= 184 + 26
= $210
Answer(s): $210
