creating a method that inserting and updating at a time

I just want to have a method that when you insert a record there's a table will update. Here is my code in my inserting record.

private void InsertReceipt()

{

decimal Stub;

Stub = Math.Floor(decimal.Parse(txtAmount.Text) / 2000);

SqlCommand cmd = new SqlCommand();

cmd.Connection = cn;

cmd.CommandType = CommandType.Text;

cmd.CommandText = "INSERT INTO Ticket(CustomerID, Date, Store, Amount, NoStub)" +

"VALUES (@CustomerID, @Date, @Store, @Amount, @NoStub) ";

cmd.Parameters.AddWithValue("@CustomerID", txtCustomerID.Text);

cmd.Parameters.AddWithValue("@Date", dtpDate.Value.Date.ToString());

cmd.Parameters.AddWithValue("@Store", txtStore.Text);

decimal amount = decimal.Parse(txtAmount.Text);

cmd.Parameters.AddWithValue("@Amount", amount);

cmd.Parameters.Add("@NoStub", SqlDbType.Decimal).Value = Stub;

cmd.ExecuteNonQuery();

}

For example this data is added to the Table "Ticket", I want to have an output that would display to the Table "StubRange".

Table "Ticket"

Table "StubRange"

Just Imagine the output and anyone can create me line of code to have this kind of output.
