So I attempted this and I'm not sure if it's the correct answer - and I don't know how to graph it..
Student tickets to the Homecoming game cost $5 each. General admission tickets cost $8 each. So far, 150 tickets have been sold. $900 has been collected.
A. Write a system of equations for this model in standard form.
Equation 1: g+s=150
Equation 2: 8g +5s = 900
B. Graph the system. (let each square represent 20 units)
C. What is the solution to the system?
(this is my attempt)
G = 150 – s
8(150-s)+5s=900
1200-8s+5s=900
-900 -900
300/3-3s/3
Answer:
100=student tickets and 50=general admission tickets
And I don't know how to check this one, or atleast how to plug it in, /to/ check it:
D.Is (180, -30) a solution? Explain.

your solution is correct.
To check on (180,-30), plug it in
8(180)+5(-30) =?= 900
But, how do you sell -30 student tickets?
