To solve this problem, I$$ll walk through the steps and how the code can structured. Here$$s the implementation:

$5.$ You are working at KFC and must enter each product sold and calculate the profit you made at the end of the day. You decided to automate the selling and calculating the profit for the day. KFC sells two products: ZINGER and CHICKEN.

$5\mathrm{.}1.$ Use the starter code provided below.

$5\mathrm{.}2.$ Create a user prompt to input a burger sale and then store the sale in a file

$5\mathrm{.}3.$ The name of the file should be your initials$\_$KFC$.$txt

$5\mathrm{.}4.$ If the user enters $$R$,$ show the total sale amount and profit, and the program stops.

$5\mathrm{.}5.$R$$ can be entered in upper$-$ or lowercase.

$5\mathrm{.}6.$ ZINGER sells for $$9\mathrm{.}95$ and costs $$4$ to make.

$5\mathrm{.}7.$ CHICKEN sells for $$12\mathrm{.}95$ and costs $$6\mathrm{.}50$ dollars to make.

$5\mathrm{.}8.$ Message to the user to enter data should be:

$5\mathrm{.}9.$ Please choose one of the following options:

$(1)$ ZINGER, $(2)$ CHICKEN, $($R$)$ Report

$>>>$

$5\mathrm{.}10.$ Message to the user after r is pressed should be $($values will vary based on sales$)$:

For Example: You made $$33\mathrm{.}0.$ The profit is $$18\mathrm{.}5$

# Ask for user input until input is input

#update the file with the product sold

def display$\_$daily$\_$profit$($FILE$\_$NAME, KFC$\_$MEAL$\_$COST, KFC$\_$MEAL$\_$PRICE, KFC$\_$CHICKEN$\_$COST, KFC$\_$ZINGER$\_$PRICE$)$:

return

# Main

KFC$\_$MEAL$\_$COST $=4\mathrm{.}00$

KFC$\_$MEAL$\_$PRICE $=10\mathrm{.}00$

KFC$\_$CHICKEN$\_$COST $=6\mathrm{.}50$

KFC$\_$ZINGER$\_$PRICE $=13\mathrm{.}00$
