7/25, 6/25, and 11/50. Looks like they are already in order, or you meant to do that... 
        
             
        
        
        
90 books would be left I believe I just took 250/9 since it would take 9 quarters to make $2.50 and since 75% was gone that would mean 25% is left so your answer is 90 unless it’s not but I believe it’s right.

Write an equation where x = Justin's orders 
93 = (x) + (2x) + (x + 5)
Simplify the equation:
93 = 4x + 5 
Subtract 5 from both sides:
88 = 4x
Divide 4 on both sides:
22 = x
Solve for the orders:
x = 22 = Justin
22(2) = 44 = Chang
22 + 5 = 27 = Heather. 
Hope this helps!
