conversations.value: I need help with this problem:
  Milly needs to return a book she decided was really boring. The book weighs 4 pounds, cost $32, and needs to be returned to a distribution center 20 miles away. If the shipping company charges $0.35 per pound plus $0.08 per mile, and Amazon will only refund 75% of the book's purchase price, how much money will Milly lose?

conversations.value: Milly will get back from Amazon $32 * .75 = $24 once the book is returned.
  She will lose $32 - 24 = $8 when the book is returned.
  The first part of the shipping cost is $0.35 per pound * 4 pounds = $1.40
  The second part of the shipping cost is $0.08 per mile * 20 miles = $1.60
  Milly loses $8 + $1.40 + $1.60 = $11
