    The algorithm in this exercise tries to answer this question:
        What is the price per page of a given book?
    The information necessary to make this calculation is inside
    a dictionary.
   
   The dictionary has three keys:
        "number_of_pages"
        "price"
        "discount"
    Put the pieces of this algorithm in the right order to calculate
    the answer.
