Answer:

100 adult tickets

150 students tickets

Step-by-step explanation:

First, construct an equation that relates the tickets.  

For the first equation, 5x represents $5 per ticket for students and 8y represents $8 per ticket for adult, showing the money earned.  

For the second equation, x represents student tickets and y represents adult tickets, showing the tickets sold.

[tex]5x+8y=1550\\x+y=250\\[/tex]

Then, you have to cancel out similar factors.  I will multiply the second equation by -5 because that is the easiest option for this specific case.

[tex]-5(x+y=250)\\-5x-5y=-1250\\5x+8y=1550\\3y=300\\y=100[/tex]

We have solved for y, which is how many adult tickets were sold.  To solve for student tickets, we will solve the second equation.

[tex]x+y=250\\x+100=250\\x=150[/tex]

As a result we have 100 adult tickets and 150 student tickets.

Hope this helps!! <3
