Why does this not work? (Python)

Question

#Gets price
price = input()
tax_rate = 6
#Caculates tax and prints
total = ((price / tax_rate) + price)
print(total)

Answer 1

input() always returns a string

Answer 2

# The int() function converts a number or a string to its equivalent integer
price = int(input())

Answer 3

SwiftSand as others mentioned, price has to get converted from string to a number by using float() (or maybe int(), depending on task requirements). I would add that the code uses tax_rate as a fraction. Is it correct? In my experience tax rate is usually a percentage.
