This is the code that I have:

using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms;

namespace Lab10 { public partial class Form1 : Form { public Form1() { InitializeComponent(); }

private void button1_Click(object sender, EventArgs e) { double addon; double maincourse; double subtotal; double total; double tax;

if (radioButton1.Checked) { maincourse = 6.95; addon = 0.75; } else if (radioButton2.Checked) { maincourse = 5.95; addon = 0.5; } else if (radioButton3.Checked) { maincourse = 4.95; addon = 0.25; } subtotal = maincourse;

if (checkBox1.Checked = true)

subtotal = subtotal + addon; if else (checkBox2.Checked = true) subtotal = subtotal + addon if else (checkBox3.Checked = true) subtotal = subtotal + addon

tax = (7.75 / 100)*subtotal total = tax + subtotal

textBox1.Text = subtotal.ToString; textBox2.Text = tax.ToString("#.##"); textBox3.Text = total.ToString("#.##"); }

private void button2_Click(object sender, EventArgs e) { Application.Exit(); }

private void checkBox3_CheckedChanged(object sender, EventArgs e) { clearTotals();

}

private void checkBox2_CheckedChanged(object sender, EventArgs e) { clearTotals();

}

private void checkBox1_CheckedChanged(object sender, EventArgs e) { clearTotals(); }

private void radioButton1_CheckedChanged(object sender, EventArgs e) { groupBox1.Text = "Add-on Item($0.75 each)"; checkBox1.Text = "Lettuce, tomato and onion"; checkBox2.Text = "Ketchup, mustard and mayo"; checkBox3.Text = "French fries";

C-Sharp University needs you to create a form that accepts a lunch order from the student and then calculates the order subtotal and total.
