Letter 'C' on this question confuses me, please help!

Holly has joined a video rental club. After paying $6 a year to join, she
then has to pay only $1.25 for each new release she rents.

a. Write an equation in intercept form to represent Holly’s cost for movie rentals.

b. Graph this situation for up to 60 movie rentals.

c. Video Unlimited charges $60 for a year of unlimited movie rentals. How many movies would Holly have to rent for this to be a better deal?

  • Math -

    I don't know if this is "intercept form," but here goes. Let x = # of rentals.

    C = 6 + 1.25x

    Cannot graph on this post.

    60 < 6 + 1.25x
