Answer:

Let C = the cost of one CD

 

We know that 5 CDs cost $20.  If one CD costs C, then 5 CDs costs 5C; that is:

 

5C = $250

 

Divide both sides of the above equation by 5:

 

C = $20/5 = $4 for one blank CD

Here is the equation

Let C= cost of one CD


So, in a pack you can get 5 for 20


So that means 5C=20

To answer this you would devide by 5 on both sides to get C=4


So the cost of one CD is $4
