I need help with this question: The cost for a certain music plan is $9.99 per year plus $0.25 per song you download. If you paid $113.74 one year find the number of songs you downloaded.
so you would make this into an equation ;
9.99+0.25s= t
s= how many songs you download
t= total cost
then you plug in your 113.74 as t;
9.99+0.25s=113.74
then you solve for s;
113.74-9.99=103.75
103.75 divided by 0.25=415
so you downloaded 415 songs
