Answer:
The question has a mistake
Step-by-step explanation:
11d+7c= 172.5
10d+7c= 155.8
By subtraction;
1d+ 0c = 16.7
1d = 16.7
11×16.7+7c=172.5
7c = 172.5-11*16.7
You will get a negative answer yet the cost cannot be negative.

Answer:

Step-by-step explanation:
Method #1
We can draw a <em>right triangle</em> on the graph upon where the points are located and use the Pythagorean Theorem:





* Whenever we talk about distance, we ONLY want the NON-NEGATIVE root.
_______________________________________________
Method #2
Or, we can use the Distance Formula:
![\sqrt{[-x_1 + x_2]^{2} + [-y_1 + y_2]^{2}} = D](https://tex.z-dn.net/?f=%5Csqrt%7B%5B-x_1%20%2B%20x_2%5D%5E%7B2%7D%20%2B%20%5B-y_1%20%2B%20y_2%5D%5E%7B2%7D%7D%20%3D%20D)
[2, 7] [3, −3]
![\sqrt{[-3 + 2]^{2} + [3 + 7]^{2}} = D](https://tex.z-dn.net/?f=%5Csqrt%7B%5B-3%20%2B%202%5D%5E%7B2%7D%20%2B%20%5B3%20%2B%207%5D%5E%7B2%7D%7D%20%3D%20D)
![\sqrt{[-1]^{2} + 10^{2}} = D](https://tex.z-dn.net/?f=%5Csqrt%7B%5B-1%5D%5E%7B2%7D%20%2B%2010%5E%7B2%7D%7D%20%3D%20D)

Hello!
First you have to find the area of the space
300 * 500 = 150000
Next you have to find the space 5 people take up
5 * 5 = 25
Divide these two numbers
150000 / 25 = 6000
multiply this by the amount of people take up that space
6000 * 5 = 30000
The answer is D)30,000 people
Hope this helps!
