Answer: 8 senior tickets, 12 normal tickets.
Step-by-step explanation:
You can find the answer to this by creating two equations: one for the amount of tickets sold and the other for how much money was collected.
I will represent the variables as A for normal tickets and C for senior tickets.
![A + C = 20\\12A + 6C = 192](https://tex.z-dn.net/?f=A%20%2B%20C%20%3D%2020%5C%5C12A%20%2B%206C%20%3D%20192)
To solve this, you can solve for one of the variables. I will solve for A in the first equation:
![A = 20-C\\12A + 6C = 192](https://tex.z-dn.net/?f=A%20%3D%2020-C%5C%5C12A%20%2B%206C%20%3D%20192)
Then, you can substitute the new value of A in the second equation:
![12(20-C) + 6C = 192\\240-12C+6C=192\\240-6C=192\\-6C=-48\\C=8](https://tex.z-dn.net/?f=12%2820-C%29%20%2B%206C%20%3D%20192%5C%5C240-12C%2B6C%3D192%5C%5C240-6C%3D192%5C%5C-6C%3D-48%5C%5CC%3D8)
Knowing that there were 8 senior tickets sold and 20 tickets sold total, we know that there were 12 normal tickets sold.
