How do you insert a function that will calculate the average retail price of the available toppings?

Answer 1

To insert a function that calculates the average retail price of available toppings, you would first need to collect the prices of the toppings into a list or array. Then, you can create a function that sums these prices and divides the total by the number of toppings. In Python, for example, the function could look like this:

def average_price(prices):
    return sum(prices) / len(prices) if prices else 0

You would call this function by passing the list of topping prices as an argument.
