John buys 20 hours of music a month. The average length of a song is 3 minutes. He buys each song for $.50. How much does he pay for music a year?
Let's be accurate as possible. Think before you answer.
2400
He buys 20 * 60 = 1200 minutes of music a month.

So that is 1200 / 3 = 400 songs.

That means he pays 400 *.

5 = $200 a month.

So it comes out to 200 * 12 = $2400 a year.

The answer is 2400
