A supermarket awards coupons depending on how much a customer spends on groceries. For example, if you spend $50, you will get a coupon worth eight percent of that amount. The following table shows the percent used to calculate the coupon awarded for different amounts spent. Write a program that calculates and prints the value of the coupon a person can receive based on groceries purchased.

Code:

import java.util.Scanner;

public class Main
{
  public static void main(String[] args) {
	Scanner input = new Scanner(System.in);
	System.out.print("Groceries cost: ");
	double groceries_c = input.nextDouble();
	input.close();
	double discount = (groceries_c < 10)? 0:
	    		  (groceries_c < 61)? groceries_c * 0.08:
	    		  (groceries_c < 151)? groceries_c * 0.10:
	    		  (groceries_c < 211)? groceries_c * 0.12:
	    		   groceries_c * 0.14;
	System.out.println("You win a discount coupon of " + discount);
    }
}
