The school that Mary goes to is selling tickets to a spring musical. On the first day of ticket sales
the school sold 6 adult tickets and 1 student ticket for a total of $82. The school took in $51 on
the second day by selling 3 adult tickets and 3 student tickets. What is the price each of one adult
ticket and one student ticket?

Answer:

The cost of one adult ticket is $13, and the price of one student ticket is $4.

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

x is the cost of an adult ticket

y is the cost of a student ticket.

6 adult tickets and 1 student ticket for a total of $82

This means that

[tex]6x + y = 82[/tex]

[tex]y = 82 - 6x[/tex]

The school took in $51 on the second day by selling 3 adult tickets and 3 student tickets.

This means that

[tex]3x + 3y = 51[/tex]

Simplifying by 3

[tex]x + y = 17[/tex]

Since [tex]y = 82 - 6x[/tex]

[tex]x + 82 - 6x = 17[/tex]

[tex]-5x = -65[/tex]

[tex]5x = 65[/tex]

[tex]x = \frac{65}{5} = 13[/tex]

[tex]y = 82 - 6x = 82 - 6*13 = 82-78 = 4[/tex]

The cost of one adult ticket is $13, and the price of one student ticket is $4.
