The school that Mary goes to is selling tickets to a spring musical. On the first day of ticket sales
andrezito [222]

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

6x + y = 82

y = 82 - 6x

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

This means that

3x + 3y = 51

Simplifying by 3

x + y = 17

Since y = 82 - 6x

x + 82 - 6x = 17

-5x = -65

5x = 65

x = \frac{65}{5} = 13

y = 82 - 6x = 82 - 6*13 = 82-78 = 4

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

X/6 + 4 = 15 what does x equal? What is x?
Umnica [9.8K]
Hello there! x = 66.

x/6 + 4 = 15

This means that since 15 - 4 = 11, x/6 = 11.

Given the two numbers and a variable, we can multiply:

6 x 11 = 66

66/6 = 11

Therefore, x = 66

Hope this helps!
