Hi,

Because of mass production, the cost to produce a certain DVD varies inversely as the number of DVDs produced.

If 4000 can be produced at a cost of $1.20 each, 

what is the costgreen%28X%29 per DVD if 6000 are produced?

   4000%281.20%29+=+6000X

   %284000%2F6000%29%281.20%29+=+X

       (2/3)$1.20 = X 

             $0.80 = X
