Jason loves to download music. Downloads R Us sells songs only in packages of three, and it charges $2.00 for each package of three songs. jason's favorite group just released their Greatest Hits CD, which has 17 songs on it. Jason wants to buy all 17 songs from Downloads R Us. How much should jason expect to pay?
If they are only sold in packages of three, 18 songs would cost $12, and they would get an extra song.
