Please check the answer section.

And If you want Rounded off value, then you need to all below code in calc_click method. Double click on calc, and code behind will appear. Add the below code over there:

double tax = Convert.ToDouble((textBox1.Text)) * 5/100;

double Roundedtax = Math.Round(tax, 2);

textBox2.Text = Convert.ToString(Roundedtax);

textBox2.Show();

textBox3.Text = Convert.ToString(Convert.ToDouble(textBox1.Text) + Convert.ToDouble(textBox2.Text));

textBox3.Show();

For dollar sign, add a label after each textbox, and change its text to $s.
