So, this is what I came up with. It works, which is good but it’s a little
different from a few things you guys had mentioned. For one, I got the correct
time by calculating the number of time run and converting that into seconds
then back out to hr:mn:sc. I didn’t calculate from midnight. T
You guys are awesome! I think I was over complicating things for one. Plus I
was looking at some code I wrote for another problem that asked to put in the
number of seconds to calculate the problem and I didn’t need some of the things
I added to this problem. Anyways, you guys have given me a
Also, can any of you reccommend sites that may have little “projects” that I
could work on to help me learn python better?

Also, any help on how to get the hours and seconds into double digits that
would be cool too. 00:00:00

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?

Thanks Chris!

Any chance you guys could help with another question I have? Below is a code
to a different problem. The only thing I don’t understand is why when
calculating the 'discounted price’ you have to subtract 1? Thanks again guys!
price_per_book = 24.95
discount = .40
quantity = 60
