3 u |
5 u |
|
Change |
+ $47 |
- $11 |
|
After |
3 u + $47 |
5 u - $11 |
8 u + $36 |
Amount of money Erika and Jane has is the same in the end.
5 u - 11 = 3 u + 47
5 u - 3 u = 47 + 11
2 u = 58
1 u = 58 ÷ 2 = 29
Amount the girls have in the end
= 3 u + 47 + 5 u - 11
= 8 u + 36
= 8 x 29 + 36
= 232 + 36
= $268
Answer(s): $268
