Answer from: jaaiphieaslade

The solution code is written in Python.

First version (user input through terminal)

food_price = float(input("Enter food price: ")) sales_tax = food_price * 0.07 tips = food_price * 0.15 total_cost = food_price + sales_tax + tips print("Food price: $" + str(food_price)) print("Sale tax: $" + str(sales_tax)) print("Tips: $" + str(tips)) print("Total cost: $" + str(total_cost)) print("\n")

Second version (input from text file)

with open("text.txt") as file: data = file.readlines() for r in data: food_price = float(r) sales_tax = food_price * 0.07 tips = food_price * 0.15 total_cost = food_price + sales_tax + tips print("Food price: $" + str(food_price)) print("Sale tax: $" + str(sales_tax)) print("Tips: $" + str(tips)) print("Total cost: $" + str(total_cost)) print("\n")

Explanation:

First version

In the first version of code, we can create all the necessary variables to hold the value of food price, sales tax, tips and total cost (Line 1 -4). Please note we get the food price using the input() function to prompt user to enter the value through terminal (Line 1).

Next display the values using print() function (Line 5 - 8)

Second version

The second version of code is similar to the first version except that we need to change the code to accept input from a text file (Line 1 -2) instead of using the input function.

We presume there might be multiple values in the text file and therefore it is recommended to use readlines() method to get the value line by line from the text file (Line 2) and use for loop to traverse through each row of food price value and calculate the sales tax, tips and total cost (Line 4-7).

Suppose s, t, and w are strings that have already been created inside main. write a statement or statements, to be added to main, that will determine if the lengths of the three strings are in order by length, smallest to largest. that is, your code should determine if s is strictly shorter than t, and if t is strictly shorter than w. if these conditions hold your code should print (the boolean value) true. if not, your code should print false. (strictly means: no ties) example: if s, t, and w are "cat", "hats", and "skies" your code should print true - their lengths are 3-4-5; but if s, t, and w are "cats" "shirt", and "trust", then print false - their lengths are 4-5-5 enter your code in the box below
