Explanation:
3x−y=12,
-y = 12 - 3x
y = 3x - 12
8x/ 2y = 4x / y
= 4x /(3x - 12)

A movie theater sells two types of tickets, adult tickets for $12 and child tickets for $8. If the
theater sold 30 tickets for a total of $300, how much was spent on Adult Tickets?
Answer:
The answer is $180.
Explanation:
Since we have two different ticket types, let's say that adult tickets represent x, and children tickets represent y. In this case, the total price would be 12x+8y that is equal to $300. We have total of 30 tickets, too. Well, then x+y should be equal to 30. Our equation system turns out to this:
12x+8y=300
x+y=30
Since we're finding the x, that is the adult tickets, we need to eliminate y by multiplying the second equation by -8. When you do that,
12x+8y=300
-8x-8y=-240
Now, you can add them.
Those y's will cancel out, and we'll be left with,
12x-8x=60
4x=60
x=15
So we found x. Let's think, the adult tickets price was $12 per. We can say that the adult tickets' price will be,
12x
In this case, 12.15 will be our answer.
It's $180.
Let's demonstrate that we found the right answer,
8y=120
y=15 too.
That assures the second equation that is 15+15=30.
The Amount spent on adult tickets in the movie theater from the given parameters is: $180
How to solve algebra word problems?Let's assume the number of adult tickets sold is A and the number of child tickets sold is C.
We are given that:
- The price of an adult ticket is $12, and as such the revenue from selling adult tickets would be 12A dollars.
- The price of a child ticket is $8, so the revenue from selling child tickets would be 8C dollars.
- The total number of tickets sold is 30, so A + C = 30.
The total revenue from selling all the tickets is $300.
We can create two equations to represent the above information:
Equation 1: 12A + 8C = 300 (total revenue equation)
Equation 2: A + C = 30 (total number of tickets equation)
Now, let's solve this system of equations to find the values of A and C:
First, we can solve Equation 2 for C:
C = 30 - A
Next, substitute this value of C into Equation 1:
12A + 8(30 - A) = 300
Now, simplify and solve for A:
12A + 240 - 8A = 300
4A = 300 - 240
4A = 60
A = 60 / 4
A = 15
So, 15 adult tickets were sold. To find out how much was spent on adult tickets, we multiply the number of adult tickets (15) by the price of an adult ticket ($12):
Amount spent on adult tickets = 15 * $12 = $180.
Therefore, $180 was spent on adult tickets.
