This is a simple question to solve.
Let's consider advanced tickets are represented by the variable "x" and same-day tickets are represented by the variable "y". So, once 1 advanced tickets + 1 same-day ticket is equal to $ 55 it means x + y = 55. Now we also have a different situation, 35 advance tickets and 40 same-day tickets were sold with a total of $2050, so 35x + 40y = 2050. We can see we have 2 equations so we have a system and we can solve is as follows:
Once we found y, we can substitute as follows:
So finally our final answer is:
advanced ticket costs $30
same-day ticket costs $25
