I want to print the value in sales
<p>I want to print the value of the amount of sales entered by user times .10. My first issue is I want to store a value that a user enters into sales then times that by .10 then print the value of sales. We I run the program I get two lines one is the amount of sales entered the other is .5. </p>

<pre><code>        const double COMMRATE = 0.10;

        string inputstring;
        double sales =5;
        char response;
        Console.Write("Do you want to Calculate Sales A or B or E...");
        inputstring = Console.ReadLine();
        response = Convert.ToChar(inputstring);
        while (response == 'A') 
        {

            Console.WriteLine("Enter Sales", sales.ToString("C"));
            sales = sales * COMMRATE;
            inputstring = Console.ReadLine();
            response = Convert.ToChar(inputstring);
        }
</code></pre>
