jonny [76]

Answer:

Step-by-step explanation:

Itunes : 0.99 per song......let d represent the number of songs

so the expression for this is : 0.99d

Napster : 10 bucks + 0.89 per song

this expression would be : 10 + 0.89d

so if u want to find out when they will be the same, set them equal to each other and solve for d

0.99d = 10 + 0.89d

0.99d - 0.89d = 10

0.10d = 10

d = 10 / 0.10

d = 100.......so 100 songs must be purchased <===

check it...

itunes :                                   napster :

0.99(100) = $ 99                 10 + 0.89(100) = 10 + 89 = $ 99

it checks out :)
