price_per_book = 24.95 discount = .40 quantity = 60 Here: discounted_price = (1-discount) * price_per_book
The discounted price should be price_per_book - discount shipping = 3.0 + (60 - 1) * .75 shipping should be, I think, should be 3.0 + (quantity * .75) total_price = 60 * discounted_price + shipping replace 60 with quantity (quantity * discounted_price) + shipping print total_price, 'Total price' total_price gives: 945.45 Total price and just 24.55(price per book - discount is ) * quantity is $1473 without the shipping, so the total is way off already: I think the following is what you're looking for: price_per_book = 24.95 discount = .40 quantity = 60 discounted_price = price_per_book-discount shipping = 3.0 + (quantity*.75) total_price = (quantity * discounted_price) + shipping print 'Total price: $%d' % (total_price) Total price: $1521 -- https://mail.python.org/mailman/listinfo/python-list
