The cost to purchase a song from iTunes is $1.98 per song.

To purchase a song from Napster, you must be a member.

The Napster membership fee is $20.

In addition, each purchased song costs $1.78

Solution 1.

Let the downloaded songs be y.

∴ 1.98y = 20 + 1.78y

1.98y - 1.78y = 20

0.2y = 20

y = 20 ÷ 0.2 = 100

So 100 songs must be downloaded from Napster.

and 100 songs must be downloaded from iTunes.

So that the monthly price of Napster can be the same as iTunes.
