Question

Write a python statement to get the price of a pizza from a user through a keyboard and store the input value in a variable called price. You should also let the user know what is expected from them to enter through a keyboard.

Answer 1

To obtain and store the price of a pizza in Python, use the following code snippet: 'price = float(input("Please enter the price of the pizza: "))'. This will prompt the user and convert their input to a float. The demand equation 'Qd = 16 - 2P' then calculates the quantity demanded at a given price.

Step-by-step explanation:

To get the price of a pizza from a user and store it in a variable called price, you can write the following Python statement:

price = float(input("Please enter the price of the pizza: "))

This code prompts the user with a message to "Please enter the price of the pizza:". The user's input is then converted into a floating-point number (to account for possible decimal values) and stored in the variable price.

The demand equation mentioned is Qd = 16 - 2P, where Qd represents the quantity demanded and P is the price of the pizzas. If you were to use this demand equation, plugging in a price of $2, would result in a quantity demanded calculation as follows:

Qd = 16 - 2*2
Qd = 16 - 4
Qd = 12

Therefore, at a price of $2 per pizza, consumers would buy 12 personal pizzas according to the demand equation provided.
