Answer:
x = 5/2     or     x = 2.5
Step-by-step explanation:
To solve for x, we will have to get the equation 2x + 15 = 20 into the form x = _. That will be our answer.
2x + 15 = 20
Subtract 15 from both sides to get rid of the +15 on the left side.
2x = 20 - 15
Simplify.
2x = 5
Divide both sides by 2 to get rid of the coefficient of 2 on the left side.\
x = 5/2 = 2.5
x = 5/2   or    x = 2.5
I hope you find my answer helpful. :)
 
        
             
        
        
        
I just figured it out so I’ll answer it on this account lol. 
Q1 = 32, Q2 = 45, Q3 = 52
Interquartile range = 52 - 32 = 20 
Range = 68 - 21 = 47
