CDs. If Paul sold 9 more CDs than John, how many CDs did John sell?

Math:

If we take away 9 CDs, then they sold equal quantities, namely (41-9)/2=16 each.

So John sold 16, and Paul sold 16+9=25 CDs.

Algebra:

Let x=number of CD's sold by John, then Paul sold x+9.

Equate total:

x+x+9=41

2x=41-9

2x=32

x=16 (John)

x+9=25 (Paul)
