This depends on how you are serving the potatoes and what part of the meal the potatoes will be. I would probably use one potato per person. I would also have an extra potato for every two men, and count half of a potato per child. That is if the potatoes were only part of the meal and not the whole meal. Being able to use math comes in handy. I would count the potatoes in a 10 pound bag and then decide how many to buy. I have also found that the different types of potatoes do better in different dishes.
I would use about 48 pounds
I would use 40 pounds.
25 pounds of potatos shoud be about right.
I would use 25 pounds of potato
it looks like 5 one pound bowls of mashed potatoes in a big heap or sumart
I would use 40 pounds and cook them cut in halves in 2-3 large pots
You need one and 1/4 potato per person, so: - serving 4 people,= 5 potatoes - serving 10 people,=12 - 13 potatoes.
One pound of of white or russet potatoes makes approximately 1 3/4 cups of mashed potatoes. Using that measurement, then five pounds of potatoes would make approximately 8 3/4 cups of mashed potatoes. Source: http://southernfood.about.com/library/info/blequivp.htm
If you are making mashed potatoes from raw potatoes, generally one potato per person. If you are using instant potatoes, then figure one cup of cooked potatoes per person.
Somewhere between 44 and 88 pounds depending on the portion size you're aiming for. How many side dishes do you have to go with it?
It depends what else they are eating. If a normal 3 veg and meat meal, then about 25 pounds of potato.
It depends on how big your potato is. If it is a large one then 1/2 a potato per person. If the potato is small then 1 potato per person.
35lb of potatoes will be enough especially mashed.
