7.

The software shall calculate the available monthly money after all the specified deductions

I have been made.

Answer 1

internal class Program
{
    static void Main()
    {
        Console.Write("Enter gross monthly income: ");
        double grossMonthly = double.Parse(Console.ReadLine());


        Console.Write("Enter the principal loan amount: ");
        double loanAmount = double.Parse(Console.ReadLine());


        Console.Write("Enter monthly interest rate: ");
        double rate = double.Parse(Console.ReadLine());


        Console.Write("Enter of payments over the loan’s lifetime");
        double n = double.Parse(Console.ReadLine());


        double monthlyPayment = loanAmount * (rate * Math.Pow(1 + rate, n) / (Math.Pow(1 + rate, n) - 1));
        if (monthlyPayment > grossMonthly / 3)
            Console.WriteLine("Approval of the home loan is unlikely.");


        Console.WriteLine($"Available money after payment: {grossMonthly-monthlyPayment}");
        Console.ReadKey();
    }


}
