Total |
Before |
3 u |
7 u |
|
Change |
+ $44 |
- $12 |
|
After |
3 u + $44 |
7 u - $12 |
10 u + $32 |
Amount of money Olivia and Xylia has is the same in the end.
7 u - 12 = 3 u + 44
7 u - 3 u = 44 + 12
4 u = 56
1 u = 56 ÷ 4 = 14
Amount the girls have in the end
= 3 u + 44 + 7 u - 12
= 10 u + 32
= 10 x 14 + 32
= 140 + 32
= $172
Answer(s): $172
