Answer: 13 + 2x = 63 and the cost of one ticket is $25 (x=25)
Explanation:
Build the equation from what it tells you.
The entire trip costs $63
The concert ticket that is included costs $13
Two passes cost the same amount, use x for what you don't know, 2x.
So, 13 + 2x = 63.
Find x = cost one pass.
13 + 2x = 63
-13. -13
2x= 50
2x/2= 50/2
x= 25
