Using Variables

Mastering variables isn't just about storing data — it's also about using this data to perform meaningful operations. Variables allow you to calculate and manipulate data, enabling you to handle tasks such as pricing adjustments or inventory management in your programs.

Let's see how Alex uses variables that store different data types:

First, let's see how we can use variables to calculate the total cost of items. This example multiplies the price per unit by the quantity to determine how much it would cost to buy a certain number of items:


              123456
            
# Calculate the total cost of 100 cupcakes
item_price = 0.50
item_quantity = 100
total_cost = item_price * item_quantity

print("Total cost for", item_quantity, "cupcakes is $", total_cost)

Task

In this challenge, you will calculate the total cost of a grocery item. This will help you practice basic arithmetic operations using the defined variables.

Fill in the placeholders (___) with the appropriate values to represent the details of the grocery item "Soda", where each case costs $6.99, and the customer intends to purchase 5 cases.

Next, use these variables to calculate the total cost of the purchase and display the result on the screen.
