In Chapter 4 , you created an interactive application named GreenvilleRevenue that prompts a user for the number of contestants entered in this years and last years Greenville Idol competition and displays the revenue expected for this years competition if each contestant pays a $25 entrance fee. The program also displays one of three appropriate statements specified in the case problem in Chapter 4, based on a comparison between the number of contestants this year and last year.

Using the GreenvilleRevenue program you wrote in Case Study 1 of Chapter 4, modify the program so that the user must enter a number between 0 and 30, inclusive, for the number of contestants each year. If the user enters an incorrect number, the program prompts for a valid value.

In order to prepend the $ to currency values, the program will need to use the CultureInfo.GetCultureInfo method. In order to do this, include the statement using System.Globalization; at the top of your program and format the output statements as follows: WriteLine("This is an example: {0}", value.ToString("C", CultureInfo.GetCultureInfo("en-US")));

using System;

using static System.Console;

using System.Globalization;

class GreenvilleRevenue

{

static void Main()

{

// Your code here

}

}
