Answer:
B)  7\8
Step-by-step explanation:
Boy interquartile range = 4
Difference between medians = 3.5
therefore,  
3.5
\4 = 7\8
 
        
             
        
        
        
If you factor the equation you can see what the solutions are.  Two factor a quadratic of the form ax^2+bx+c, find two values which satisfy two conditions...
jk=ac=-15 and j+k=b=-2 so j and k must be -5 and 3 so the factors are:
(x-5)(x+3)
So the other solution is x=5
