5 u |
|
Change |
+ $39 |
- $11 |
|
After |
3 u + $39 |
5 u - $11 |
8 u + $28 |
Amount of money Esther and Cindy has is the same in the end.
5 u - 11 = 3 u + 39
5 u - 3 u = 39 + 11
2 u = 50
1 u = 50 ÷ 2 = 25
Amount the girls have in the end
= 3 u + 39 + 5 u - 11
= 8 u + 28
= 8 x 25 + 28
= 200 + 28
= $228
Answer(s): $228
