How many ways do you think that there are?
Act I - Study the menu image on the right and consider what sort of burger you would like and how many ways you could choose your ingredients.
For toppings, you are allowed none, one, or any number of them. But for the bun, you can only choose one.
Act II - Look for a pattern in calculating how many ways both for when you could have only one and when you could have any number of sauces, toppings, yummy, etc.
Act III - Show your conclusions to the class and compare answers.
