<PRE><B>Question 389325</B>
The cost to purchase a song from iTunes is $0.99 per song. To purchase a song from Napster, you must be a member. The Napster membership fee is $10. In addition, each purchased song costs $0.89. How many songs must be purchased so that the costs are the same?
.
Let n = number of songs purchased
then

10+.89n = .99n

10 = .10n

10/.10 = n

100 songs = n
