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.

The data in the graph support the authors' point in paragraph five (lines 47–58 (“As the new kid on the block, LiDAR has been tacked onto the back end—initially thought of as kind of large-scale helper to field surveys. Carbon estimates from the field have been treated as something inherently closer to the real thing than measurements made by LiDAR—ground “Truth” with a capital “T”. This is perhaps understandable historically, but vis-à-vis actual carbon, there is no such thing as ground truth: both field and LiDAR efforts rely on allometry to convert measurements into carbon estimates.
