Answer:
21 child tickets.
Step-by-step explanation:
Let x represent number of adult tickets and y represent number of child tickets.
We have been given that on Thursday, three times as many adult tickets as child tickets were sold. We can represent this information in an equation as:

We have been given that at a the movie theater, child admission is $6.10 and adult admission is $9.20.The all tickets were sold for a total of $707.70. We can represent this information in an equation as:
Upon substituting equation (1) in equation (2), we will get:




Therefore, 21 child tickets were sold on Thursday.
Hi.
I'm going to tell you the process, since I don't have a calculator on me. Don't wanna risk it, lol.
We can break this shake into 2 parts: a rectangle, and a triangle.
To separate them, just calculate the area of the rectangle with 4 km & 3.5 km
Since the triangle's area is half that of the rectangle, all we need to do is divide the area of the rectangle by 2 to get the area of the triangle (it's confusing when in words, eh?)
Once you find the area of both, add them together.
This should get you the area of the shape.
I hope this helped. Once again, please let me know if there are mistakes.
