Before |
3 u |
5 u |
|
Change |
+ $50 |
- $6 |
|
After |
3 u + $50 |
5 u - $6 |
8 u + $44 |
Amount of money Cindy and Joelle has is the same in the end.
5 u - 6 = 3 u + 50
5 u - 3 u = 50 + 6
2 u = 56
1 u = 56 ÷ 2 = 28
Amount the girls have in the end
= 3 u + 50 + 5 u - 6
= 8 u + 44
= 8 x 28 + 44
= 224 + 44
= $268
Answer(s): $268
