C=1500+4x where x is cds, C is cost
R=10x where R is revenue
then, P=R-C
P=10x-1500-4x
P=6x-1500
set P=0
1500=6x
x=250
check, C=1500+4*250, R=10*250
C=250, R=250
They need to sell 250 cds before they make profit
        
                    
             
        
        
        
Divide the perimeter by 2, this will give you the sum of one length and one width.
68/2 = 34 yards
Now the length is  10 yards more, so subtract 10 from the 34 and divide by 2 again:
34 - 10 = 24
24 /2 = 12
The width is 12 yards.
 The length is 12 + 10 = 22 yards.
