编写一个程序，读入一笔费用与酬金率，计算酬金和总钱数。例如，如果用户输入10作为费用，15%作为酬金率，计算结果显示酬金为￥1.5，总费用为￥11.5。下面是一个运行示例：Enter the subtotal(费用) and a gratuity rate(酬金率): 15.69 15The gratuity（酬金） is 2.35 and total（总费用） is 18.04提示：java.util.Scanner input = new java.util.Scanner(System.in);input.nextDouble();变量名：subtotal(费用); rate(酬金率); gratuity(酬金); total(总费用);

import java.util.Scanner;
public class Dome2_5 {
    public static void main(String[] args) {
        // TODO code application logic here
        Scanner in = new Scanner(System.in);
        System.out.print("Enter the subtotal and a gratuity rate:");
        double subtotal = in.nextDouble();
        double gratuityrate = in.nextDouble();
        double  gratuity = subtotal * gratuityrate / 100;
        System.out.println("The gratuity is $" + gratuity + " and total is $" + (subtotal+gratuity)); 
    }
}

sum=金额*(1.15)
