# Help with a python code

I'm reading this python book called "Python for software design" and it has the following exercise:

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

ok, i have the following 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)
``````

With that I get the following results:

• The total price for 60 books including shipping and discount is:

• Total price of the books is: 898.2

• Total Shipping is: 47.25

• The Total price is: 945.45

• My questions are:

• Is this correct?

• How can i make this code better?

2) Print you results like this: `print 'The total price is: %.2f' % result`
