conversations.value: Nancy is returning her overdue books to the library. She owes $0.50 cents each on 8 books, plus a flat $2.00 fee for having at least one book that's over a week overdue. How much does she have to pay total?

conversations.value: First multiply the late fee per book by the number of books: $0.50/book * 8 books = $4.00
  Then add the "more than a week overdue" fee to the answer from the previous step to find the total: $4.00 + $2.00 = $6.00
