Answer:
Sadie took 47 minutes to finish her test.
Step-by-step explanation:
Let Laura's time be x minutes.
Then we have:
x + 3x - 16 = 68
4x = 84
x = 21 minutes.
So Sadie took 3(21) - 16 = 63-16
= 47 minutes.
 
        
             
        
        
        
A is the minimum value
B is the first quartile
The point with the line through it (next to C) is the median. 
The point to the outside of the box is the third quartile.
D is the maximum value.
Hope this helped.
