Before |
1 u |
7 u |
|
Change |
+ $25 |
- $11 |
|
After |
1 u + $25 |
7 u - $11 |
8 u + $14 |
Amount of money Vanessa and Xuan has is the same in the end.
7 u - 11 = 1 u + 25
7 u - 1 u = 25 + 11
6 u = 36
1 u = 36 ÷ 6 = 6
Amount the girls have in the end
= 1 u + 25 + 7 u - 11
= 8 u + 14
= 8 x 6 + 14
= 48 + 14
= $62
Answer(s): $62
