It will take #100# songs for the monthly price of Napster to cost the same as iTunes.

Let's create two equations to represent iTunes (#T(d)#) and Napster (#N(d)#):

#T(d)=0.99d#
#N(d)=0.89d+10#

In order for us to find when the two prices will be the same, let's set the equations equal to each other and solve for #x#:

#0.99d=0.89d+10#
#0.1d=10#
#d=100#

Hope this helps!!
