B.) A monthly service fee to download e-books is $4.95, plus $3.99 per book downloaded. WRite an equation that represents the total cost, c, in a month when b books are downloaded. Explain how your equation represents the problem. c=4.95+3.99b

When there are no books, the service fee still applies, so when b=0, c=$4.95.
For each book downloaded $3.99 is added to the charge. The service fee is only charged once a month.

c.) Create a graph of your equation from part b.

Is your graph discrete or continuous? Explain why you chose this type of graph.
