Question:
The local community theater sold a total of 240 tickets for Saturday night’s performance. They sold 180 more full-price tickets than discount tickets. Which system of equations can be used to model this situation?
Answer:
[tex]x = 180 + y[/tex]
[tex]x + y = 240[/tex]
Step-by-step explanation:
Given
[tex]Tickets = 240[/tex]
Represent the number of full price with x and discounted price with y.
From the question:
x = 180 more than y
So:
[tex]x = 180 + y[/tex]
Also, a total of 240 were sold.
So:
[tex]x + y = 240[/tex]
Hence, the equations are:
[tex]x = 180 + y[/tex]
[tex]x + y = 240[/tex]
Solving further;
Substitute 180 + y for x in [tex]x + y = 240[/tex]
[tex]180 + y + y = 240[/tex]
[tex]180 + 2y = 240[/tex]
Solve for 2y
[tex]2y = 240 - 180[/tex]
[tex]2y = 60[/tex]
Divide through by 2
[tex]y = 30[/tex]
Recall that: [tex]x = 180 + y[/tex]
[tex]x = 180 + 30[/tex]
[tex]x = 210[/tex]
Hence:
Full Price = 210
Discounted = 30
