Answer:
A. Comedy
Step-by-step explanation:
We are given that,
Movie type Number of movies
Comedy 8
Action 6
Fantasy 5
Drama 1
Then the total number of movies = 8+6+5+1 = 20
<h3><em>So, we will find the ratio of each type of movie out of total movies.</em></h3>
Ratio of comedy movies = 
Ratio of action movies = 
Ratio of fantasy movies = 
Ratio of drama movies = 
Since, we have,
<h3>Ratio of comedy movies =

</h3>
Thus, 'For every 5 movies on the list, there are 2 COMEDY movies'.
So, option A is correct.
A,B and E
Explanation:
If it is 4 for $5 we would create a ratio and unit rate to test out all of the options
We want to know how much one costs first
4/5 = 1/$1.25
So you test out all options:
A. 1.25/1=6.25/5 this is correct
B. 1.25/1=3.75/3 this is correct
C. 1.25/1=9/6 this is NOT correct
D. 1.25/1=1.5/1 this is NOT correct
E. 1.25/1=12.5/10 this is correct
Step-by-step explanation:
mC=36
mC+mD=90
36+mD=90
mD=54
