Question

 I need know how to make A  Java 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.

* - Up to 10 dollars: No coupon
* - From 10 to 60 dollars: 8% coupon
* - From 50 to 150 dollars: 10% coupon
* - From 150 to 210 dollars: 12% coupon
* - More than 210 dollars: 14% coupon

import java.util.Scanner;

public class GroceryStore {

        public static void main(String[] args) {
                
                Scanner in = new Scanner(System.in);

                System.out.println("Enter the amount of groceries you purchased: ");
                double amount = in.nextDouble();
                
                double perc = 0;
                
                if(amount >= 210) {
                        perc = 14;
                } else if(amount >= 150) {
                        perc = 12;
                } else if(amount >= 50) {
                        perc = 10;
                } else if(amount >= 10) {
                        perc = 8;
                }
                
                double discount = amount * perc / 100;
                System.out.println("You will get coupon worth $" + discount);
                
                in.close();
        }

}
