Hi there!
To solve this problem, we need to find the amount of classmates out of the entire class who did not choose blue as their favorite color and then convert it into a percentage. 
First, let's find the fraction:
Since there are 25 total people in her class, since
6 + 9 + 10 = 25
25 is the denominator of the fraction;
Since there are 16 people who did not choose blue,
6 + 10 = 16
16 is the numerator of the fraction. 
So, our fraction is 16/25. 
Now, we need to convert it into a percentage. To do this, we need to make the denominator 100 by multiplying it by a certain number, and then multiplying the numerator by that same number so the fraction stays equal:
16/25 
= 16*4/25*4
= 64/100
= 64%
So, the answer is 64% of Stephanie's classmates.
Hope this helps!
        
             
        
        
        
Answer:
x = 19
Step-by-step explanation:
A circle has a total of 360 degrees. Because central angles are congruent to the degree measures of their arcs, and because of vertical angles we can construct the equation :
5x+37+5x+37+3x-9-9=360
We can simplify this to :
8x+28=360
Subtract 28, divide 8, and x is 19
 
        
             
        
        
        
4/5 of the original amount at the start of the month will remain. The amount at the start of every month will change. Thus:
an = 4/5 (an-1) ; where a1 = 500.
