Total |
Before |
1 u |
8 u |
|
Change |
+ $46 |
- $10 |
|
After |
1 u + $46 |
8 u - $10 |
9 u + $36 |
Amount of money Xylia and Roshel has is the same in the end.
8 u - 10 = 1 u + 46
8 u - 1 u = 46 + 10
7 u = 56
1 u = 56 ÷ 7 = 8
Amount the girls have in the end
= 1 u + 46 + 8 u - 10
= 9 u + 36
= 9 x 8 + 36
= 72 + 36
= $108
Answer(s): $108
