35 as much money as Xuan. Winnie received another $26 from her father and Xuan spent $6 on some files. In the end, Winnie and Xuan had an equal amount of money. How much money did the girls have altogether in the end?

5 u |
|
Change |
+ $26 |
- $6 |
|
After |
3 u + $26 |
5 u - $6 |
8 u + $20 |
Amount of money Winnie and Xuan has is the same in the end.
5 u - 6 = 3 u + 26
5 u - 3 u = 26 + 6
2 u = 32
1 u = 32 ÷ 2 = 16
Amount the girls have in the end
= 3 u + 26 + 5 u - 6
= 8 u + 20
= 8 x 16 + 20
= 128 + 20
= $148
Answer(s): $148
