using System;

namespace TrainingHallEquipment

    class Program
    {
        static void Main(string[] args)
        {
            double budget = double.Parse(Console.ReadLine());
            int numberOfItems = int.Parse(Console.ReadLine());
            int counter = 1;
            double tempPrice = 0.00;
            double subtotalPrice = 0.00;
            do
            {
                tempPrice = 0.00;
                string itemName = Console.ReadLine();

            } while (counter != numberOfItems + 1);
            Console.WriteLine($"Subtotal: ${subtotalPrice:F2}");
