Henry's Hamburger Heaven offers its hamburgers with the following condiments: ketchup, mustard, mayonnaise, tomato, lettuce, pickles, cheese, and onions. A customer can choose one, two, or three meat patties, and any collection of condiments. How many different kinds of hamburgers can be ordered?
+36915 Here is my take
3 choices of patty 3 x
9 choices of condiment (I included NO condiment) = 9!
3 x 9! =.......
+36915 Too bad you do not have enough imagination or problem solving ability or understanding of how the question was solved to try a slightly different answer where 'no condiment' is not an option..... like 3 x 8!
