5 u |
|
Change |
+ $40 |
- $12 |
|
After |
1 u + $40 |
5 u - $12 |
6 u + $28 |
Amount of money Xylia and Tiffany has is the same in the end.
5 u - 12 = 1 u + 40
5 u - 1 u = 40 + 12
4 u = 52
1 u = 52 ÷ 4 = 13
Amount the girls have in the end
= 1 u + 40 + 5 u - 12
= 6 u + 28
= 6 x 13 + 28
= 78 + 28
= $106
Answer(s): $106
