25.12 is the answer !!!!!!
Let there be a advanced tickets and s same day tickets, Then:-
a + s = 40
20a + 30s = 950............................(1)
Multiply first equation by -30
-30a - 30x = -1200 .....................(2)
Adding equations (1) and (2):-
-10a = - 250
a = -250/-10 = 25
So s = 40 - 25 = 15
Answer:- advanced tickets cost $25 and same day cost $15.

- Multiply the denominators so make them 2921.
(127) 6/23 - 15/127(23)
762/2921 - 345/2921
- Subtract the numerators.
417/2921
