Before |
3 u |
8 u |
|
Change |
+ $29 |
- $11 |
|
After |
3 u + $29 |
8 u - $11 |
11 u + $18 |
Amount of money Gabby and Kylie has is the same in the end.
8 u - 11 = 3 u + 29
8 u - 3 u = 29 + 11
5 u = 40
1 u = 40 ÷ 5 = 8
Amount the girls have in the end
= 3 u + 29 + 8 u - 11
= 11 u + 18
= 11 x 8 + 18
= 88 + 18
= $106
Answer(s): $106
