using static System.Console;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace MoveEstimator
{
    class MoveEstimator
    {
        static void Main(string[] args)
        {
            const  int baserate=200;
            const int rateperhour = 150;
            const int ratepermile = 20;
            
            int totalhourrate, totalmiles;
            for (int numhours=1, nummiles = 1;  numhours <= 24 && nummiles <= 100; numhours++,nummiles++)
            {
                WriteLine("Enter the number of hours worked", numhours);
                ReadKey();
                totalhourrate = numhours * rateperhour;
                WriteLine("\nTotal rate of hours worked: " + totalhourrate);
               

           
                WriteLine("\n Enter the number of miles", nummiles);
                ReadKey();
                totalmiles = nummiles * ratepermile;
                WriteLine("\n Total miles covered: " +totalmiles);
                
                  

            }
            ReadLine();
            int totalfee = baserate + totalhourrate + totalmiles;
            WriteLine("\n The total fee is: " +totalfee);
            ReadKey();


        }
    }
}

You should move line #17 ("int totalhourrate, totalmiles;")
to just before line #11 ("static void Main(string[] args)")
and add 'private static ' in front of it.

Or you could initialize those vars at line #17, changing that line to:

int totalhourrate = 0, totalmiles = 0;

The explanation about this is here: CS0165
The C# compiler does not allow the use of uninitialized variables. If the compiler detects the use of a variable that might not have been initialized, it generates compiler error CS0165. ...

[Ishan Shah]

Local variables aren't initialized. so, You have to manually initialize them because members are initialized but locals are not. That's why you get the compiler error.

int totalhourrate, totalmiles; //This is not initialized and must be assigned before used.

So your code must be like the following :

int totalhourrate=0;
int totalmiles=0;
