Before |
3 u |
5 u |
|
Change |
+ $47 |
- $9 |
|
After |
3 u + $47 |
5 u - $9 |
8 u + $38 |
Amount of money Kimberly and Gem has is the same in the end.
5 u - 9 = 3 u + 47
5 u - 3 u = 47 + 9
2 u = 56
1 u = 56 ÷ 2 = 28
Amount the girls have in the end
= 3 u + 47 + 5 u - 9
= 8 u + 38
= 8 x 28 + 38
= 224 + 38
= $262
Answer(s): $262
