title: Help with a python code
body: <p>I'm reading this python book called "Python for software design" and it has the following exercise:</p>
  
  <blockquote>
    <p>Suppose the cover price of a book is $24.95, but the bookstores get a 40% discount.
    Shipping costs $3 for the first copy and 75 cents for each additional copy. What
    is the total wholesale cost for 60 copies</p>
  </blockquote>
  
  <p>ok, i have the following code:</p>
  
  <pre><code>bookPrice = 24.95
  discount = .60
  shippingPriceRest = .75
  shippingPriceFirst = 3.00
  totalUnits = 60
  
  bookDiscountAmount = bookPrice * discount * totalUnits
  shipping = shippingPriceRest * 59 + shippingPriceFirst
  
  result = bookDiscountAmount + shipping
  
  
  print 'The total price for 60 books including shipping and discount is: '
  print 'Total price of the books is: ' + str(bookDiscountAmount)
  print 'Total Shipping is: ' + str(shipping)
  print 'The Total price is: ' + str(result)
  </code></pre>
  
  <p>With that I get the following results:</p>
  
  <ul>
  <li>The total price for 60 books including shipping and discount is: </li>
  <li>Total price of the books is: 898.2</li>
  <li>Total Shipping is: 47.25</li>
  <li><p>The Total price is: 945.45</p></li>
  <li><p>My questions are: </p>
  
  <ul>
  <li>Is this correct? </li>
  <li>How can i make this code better?</li>
  </ul></li>
  </ul>
