Step-by-step explanation:
Not exactly knowing about it
x
---- = 5 (solve for x)
0.6
x = 5(0.6)
x = 3
then....
3
----- = 15
0.2

hope this helps :)
Let
x-------> the first number
y------> the second number
we know that
equation 
equation 
substitute equation 1 in equation 2
using a graph tool-----> to resolve the second order equation
see the attached figure
the solution is
The total area is given by:
A1 = (300) * (500)
A1 = 150000 feet ^ 2
The area occupied by 5 people is:
A2 = (5) * (5)
A2 = 25 feet ^ 2
Then, we can make the following rule of three:
5 --------> 25
x --------> 150000
Clearing x we have:
x = (150000/25) * (5)
x = 30000
Answer:
D. 30,000 people
