Input-Output Design for Restaurant Bill Split

Create an Input output design for the following problem statement. Hint: There should be a total of 7 variables. The output should have 6 variables – the overall bill, tip, and total and then the split amount for all three of these for each member of the party.

Problem Statement: Imagine that you and a number of friends go to a luxury restaurant, and when you ask for the bill you want to split the amount and the tip (15 percent) between all. Your program should print the amount of the bill, the tip, the total cost, and the amount each person has to pay. It should also print how much of what each person pays is for the bill and for the tip.

To design the input-output structure for the given problem statement, we will define the variables needed for input and output. The program will take the total bill amount and the number of people in the party as inputs, and it will calculate the tip, total cost, and the split amounts for each person.

Input Variables

1. bill_amount: The total amount of the bill (float).
2. number_of_people: The number of people in the party (integer).

Output Variables

1. tip: The calculated tip amount (float).
2. total_cost: The total cost including the bill and the tip (float).
3. split_amount: The amount each person has to pay (float).
4. bill_per_person: The amount each person pays for the bill (float).
5. tip_per_person: The amount each person pays for the tip (float).
6. individual_contribution: A detailed breakdown of what each person pays (dictionary or list of tuples).

Input-Output Design

Input

• bill_amount: (e.g., 200.00)
• number_of_people: (e.g., 4)

Output

• tip: (e.g., 30.00)
• total_cost: (e.g., 230.00)
• split_amount: (e.g., 57.50)
• bill_per_person: (e.g., 50.00)
• tip_per_person: (e.g., 7.50)
• individual_contribution:
  • Example:

    [
        {"person": 1, "bill": 50.00, "tip": 7.50},
        {"person": 2, "bill": 50.00, "tip": 7.50},
        {"person": 3, "bill": 50.00, "tip": 7.50},
        {"person": 4, "bill": 50.00, "tip": 7.50}
    ]
    

Example Calculation

Given the inputs:

• bill_amount = 200.00
• number_of_people = 4

The calculations would be as follows:

1. Tip Calculation:

   • tip = bill_amount * 0.15 = 200.00 * 0.15 = 30.00

2. Total Cost Calculation:

   • total_cost = bill_amount + tip = 200.00 + 30.00 = 230.00

3. Split Amount Calculation:

   • split_amount = total_cost / number_of_people = 230.00 / 4 = 57.50

4. Bill and Tip per Person:

   • bill_per_person = bill_amount / number_of_people = 200.00 / 4 = 50.00
   • tip_per_person = tip / number_of_people = 30.00 / 4 = 7.50

5. Individual Contribution:

   • Each person pays 50.00 for the bill and 7.50 for the tip.

Summary

This input-output design provides a clear structure for the program to follow, ensuring that all necessary calculations are made and that
