A burger place offers its burgers with the choice of one, two, or three meat patties. Customers may add any (as many or none as they choose)
of the following condiments: ketchup, mustard, tomato, lettuce, pickles, mayonnaise, cheese, and onions. How many different kinds of hamburgers can be ordered?
We are given,
burgers with three types of meat patties = 3
and types of condiments: ketchup, tomato, lettuce, pickles, mayonnaise, cheese, and onions = 7
i.e.
1 meat patties without any condiment(ketchup, tomato, lettuce, pickles, mayonnaise, cheese, and onions) =
1 meat patties with any single condiment(ketchup, tomato, lettuce, pickles, mayonnaise, cheese, and onions) =
1 meat patties with any two condiment(ketchup, tomato, lettuce, pickles, mayonnaise, cheese, and onions) =
1 meat patties with any three condiment(ketchup, tomato, lettuce, pickles, mayonnaise, cheese, and onions) =
1 meat patties with any four condiment(ketchup, tomato, lettuce, pickles, mayonnaise, cheese, and onions) =
1 meat patties with any five condiment(ketchup, tomato, lettuce, pickles, mayonnaise, cheese, and onions) =
1 meat patties with any 6 condiment(ketchup, tomato, lettuce, pickles, mayonnaise, cheese, and onions) =
1 meat patties with all condiment(ketchup, tomato, lettuce, pickles, mayonnaise, cheese, and onions) =
So, total hamburgers with 1 meat patties can be ordered = 1+7+21+35+35+21+7+1 = 128 Hamburgers.
Similarly,
So, total hamburgers with 2 meat patties can be ordered = 1+7+21+35+35+21+7+1 = 128 Hamburgers.
So, total hamburgers with 3 meat patties can be ordered = 1+7+21+35+35+21+7+1 = 128 Hamburgers.
Overall total hamburgers can be ordered (with different meat patties and different condiments or without it) = 128+128+128 = 384 Hamburgers.
