How do I convert a user-entry from an input box on Tkinter, into an integer? I keep getting "TypeError: unsupported operand type(s) for /: 'Radiobutton' and 'int'

It would be helpful to solve your problem, if you could post your code.

Here is my code. I really was not sure what I was doing as I am just getting into coding, but my goal was to create a simple meal calculator. The user would select either a percent tip or a specific amount with a radiobutton, and then enter the value. The program runs, but in the end it won't calculate anything out. 

from tkinter import *
import math

class MyFrame(Frame):
    def __init__(self):
        Frame.__init__(self)
        self.master.geometry("600x400")
        self.master.title("Restaurant Bill Calculator")
        self.grid()

        self.welcome_message = Label(self, text ="Welcome to the Tip Calculator!")
        self.welcome_message.grid(row = 1, column = 1)

        self.meal_cost

    def meal_cost(self):
        self.meal_cost = Label(self, text ="Please enter the total bill for your meal:")
        self.meal_cost.grid(row = 2, column = 1)

        self.meal_cost_input = IntVar()
        self.meal_cost_input = Entry(self)
        self.meal_cost_input.grid(row = 3, column = 1)

        self.submit_button = Button(self, text = "Submit", command = self.submit_click)
        self.submit_button.grid(row = 4, column = 1)

    def submit_click(self):
        self.message = Label(self, text = "Okay, meal cost was: $" + self.meal_cost_input.get())
        self.message.grid(row = 7, column = 1)

        self.tip_message = Label(self, text ="Next, choose how you would like to tip:")
        self.tip_message.grid(row = 8, column = 1)

        self.percent_tip = Radiobutton(self, text = "% tip", command = self.tip_calculate_percent)
        self.percent_tip.grid(row = 9, column = 1)

        self.amount_tip = Radiobutton(self, text = "Amount", command = self.tip_calculate_amount)
        self.amount_tip.grid(row = 9, column = 2)

    def tip_calculate_percent(self):
        self.percent_box = Label(text = "What percent would you like to tip?")
        self.percent_box.grid(row = 10, column = 1)

        self.percent_box_input = IntVar()
        self.percent_box_input = Entry(self)
        self.percent_box_input.grid(row = 11, column = 1)
        self.submit_button_two = Button(text = "Done", command = self.percent_done_click)
        self.submit_button_two.grid(row = 12, column = 1)


    def tip_calculate_amount(self):
        self.amount_box = Label(text = "How much would you like to tip?")
        self.amount_box.grid(row = 10, column = 1)

        self.amount_box_input = IntVar()
        self.amount_box_input = Entry(self)
        self.amount_box_input.grid(row = 11, column = 1)
        self.submit_button_two = Button(text = "Done", command = self.percent_done_click)
        self.submit_button_two.grid(row = 12, column = 1)


    def percent_done_click(self):
        self.total_price = self.meal_cost_input + (self.meal_cost_input) * (self.percent_tip / 100)
        self.total_price_box = Label(text = "Cost per person is: {}".format(total_price))
        self.total_price_box.grid(row = 13, column = 1)

    def amount_done_click(self):
        self.total_price = meal_cost_input + amount_tip
        self.total_price_box = Label(text = "Cost per person is: {}".format(total_price))
        self.total_price_box.grid(row = 14, column = 1)
