Change |
+ $41 |
- $11 |
|
After |
1 u + $41 |
5 u - $11 |
6 u + $30 |
Amount of money Irene and Min has is the same in the end.
5 u - 11 = 1 u + 41
5 u - 1 u = 41 + 11
4 u = 52
1 u = 52 ÷ 4 = 13
Amount the girls have in the end
= 1 u + 41 + 5 u - 11
= 6 u + 30
= 6 x 13 + 30
= 78 + 30
= $108
Answer(s): $108
