Julien Coleman · Answer 1

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

Armani Golden · Answer 2

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
