Question at position 14 A function named get_change has already been defined in the program. The function has the following signature: get_change(item_name: str, amount_paid: float) - float If the missing lines are filled in correctly, the program should ask the user for the item name and the customer’s amount_paid, then uses the get_change function to calculate how much change to return to the customer. Finally, it should display the change formatted to two decimal places. [table]
# get_price defined above5 def main():6 name = input('Enter the item name: ')7 paid = input('Enter the amount the customer paid: ')8 # ( code WILL go here )9 print(f'You will receive {result:.2f} change.')10 11 main()

The question describes a small program flow where we collect two inputs from the user and then call get_change to compute the change, finally printing it with two decimal places.
Option A: 'result = get_change(name, paid)'. Here, paid is the raw string returned by input. Since get_change expects amount_paid to be a float, passing a string could cause a type error or incorrect calculation unless get_change handles strings. Therefore this is unlikely to be correct.
Option B: 'get_change(name, float(paid), result)'. This call injects a third argument result, which does not match the function signature get_change(item_name: str, amount_paid: float) -> float. Passing an extra parameter would cause a TypeError. This option is inconsistent with the defined function.
Option C: 'result = get_change(item_name, amount_paid)'. The variables item_name and amount_paid do not exist in main as defined; the code uses name for the item and paid for the amount, so this would raise a NameError. Additionally, amount_paid would be a string unless converted, so even if names matched, the types would be wrong.
Option D: 'result = get_change(name, float(paid))'. This option uses the correct item_name variable (name) and converts the input amount to a float (float(paid)) to satisfy the function’s expected float parameter. The assignment to result matches the expected pattern, and the following print statement uses result formatted to two decimals, which aligns with the described goal. This pairing is consistent with the function signature and the surrounding code structure.
In summary, the only option that aligns with the function signature, proper type handling, and the surrounding code variables is the one that converts the paid input to float and passes name as the item_name: result = get_change(name, float(paid)).
