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
discounted_price = (1-discount) * price_per_book
shipping = 3.0 + (60 - 1) * .75
total_price = 60 * discounted_price + shipping
print total_price, 'Total price'
