Lab 2 – Restaurant Bill (3%)

Define the problem and outline the solution for the given scenario.

  • You are asked to design an algorithm that calculates the total amount of a meal. It asks to enter the charges for the food purchased in dollars and cents. Calculate the sales tax of 7% and display it. Calculate the tip of 15% and display it. Sales tax and tip must be calculated separately on the total amount of meal purchased. Finally, it displays the total amount after tax and tip is included.
  • You can use the following table format to define the problem and then outline a solution.
Input Processing Output
  • Write pseudocode or Java program to develop the outline into an algorithm.
  • Declare and use constants in pseudocode/Java program as appropriate.
  • Here are the two sample screen shots:

1.
How much does the meal cost?
235.78
Net Amount(excluding tax): $235.78
Tax (7%): $16.50
Tip (15%): $35.37
Gross Amount (including tax and tip): $287.65

2.
How much does the meal cost?
300
Net Amount(excluding tax): $300.0
Tax (7%): $21.00
Tip (15%): $45.00
Gross Amount (including tax and tip): $366.00

Note: Numbers in green font are inputs and with normal font are outputs. In Java, we use double as a data type to represent a decimal number.
