Question

Write a program that reads the subtotal and the gratuity rate for a service. Compute the gratuity and the total. For example, if the user enters 10 for the subtotal and 15% as the gratuity rate, the program displays $1.5 as the gratuity and $11.5 as total. Your program should output the subtotal entered, the gratuity rate, the gratuity amount and the total amount due.

Answer 1

//Gratuity.java
import java.util.Scanner;
public class Gratuity {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        double subtotal, gratuityRate, gratuity, total;

        System.out.print("Enter the subtotal: ");
        subtotal = input.nextDouble();
        System.out.print("Enter the gratuity rate: ");
        gratuityRate = input.nextDouble();

        gratuity = subtotal * (gratuityRate / 100);
        total = subtotal + gratuity;

        System.out.printf("The gratuity is $%.1f and total is $%.1f\n", gratuity, total);
    }
}
