figure out how many onions are needed for one burger then either multiply that by a hundred or divide a hundred by that
Ten
If this are whole pickles and can be sliced into 5 pieces, we can say 2 slices per hamburger. At 50 hamburgers we need 100 slices. 100/5 = 20 pickles.
25 tomatoes
25 to 30 tomatoes will yield enough slices for 100 hamburgers at 2 slices per burger.
The average American eats about 100 hamburgers a year. If you multiply that by the average lifespan (about 78 years) it would be about 7,800 hamburgers in a lifetime.
Hot dogs do not contain hamburger meat. If you mean how many hamburgers should you have to go with 100 hot dogs, you would want 100 hamburgers.
35
A minimum of 50. Personally I would say 100 Hot dogs and 100 hamburgers. That way if they want more they can have more.
Are you going to confine them to 1 each, or allow more. -100-200 depending.
400
It depends on how many kids and adults there are say 1 1/2 is what one kid eats. 2 is what an adult eats. count it up and you will know.Hot dogs: 200( so people can have seconds)Hamburgers: 200 (so people can have seconds)
Assume that each person will eat one hamburger, you would need 200 hamburgers, plus the buns. Then at least 100 to 200 extra hamburgers and buns for those who want more! Keep a hundred of the extras in the freezer in case they are not needed. Always err on the high side, as it looks bad to run out!
