685-85=600
1 year =12 months 
12 multiply by 2 =24
600 divided by 24=25
answer=25
        
                    
             
        
        
        
The answer is 408. One way to solve is to do 8*50 and then do 8*1 and add the products together.
        
             
        
        
        
Y=cd-8
Add 8 to each side giving you 
y+8=cd
Divide by d on each side giving you 
C=(y+8)/d
