discount = .40

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)

Or a better iterating example for a database of shipping, or ordering books
would be:
import random as r
def
order_total(price_per_book,percent_discount_amount,quantity,first_book_shipping,extra_book_shipping):
percent_discount = price_per_book * percent_discount_amount
Should have been the following, which just shows the books price as a float as
well, but you get the point by now, I'm sure:
import random as r
def
order_total(price_per_book,percent_discount_amount,quantity,first_book_shipping,extra_book_shipping):
percent_discount = price_per_book *

Yeah you’re right I didn’t even notice that. For some reason I just added the
60 instead of using quantity which had been defined.

Once you can divide the number of seconds into hours, minutes, and

If you’re interested in what the problem is here it is…
Suppose the cover price of a book is $24.95, but 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?
