If everyone is to get a single serving of 200g fries, you'll need around 6 kilogram:
200 g * 30 = 6.000 kg
Word of advice: Do not attempt to actually prepare 6kg worth of fries all at once; It will not work and will only result in tears and despair. Trust me.
I would make 38-40 pounds
To make cheesy potato casserole most recipes require about 2 pounds of potatoes to feed 8 people. If you are feeding 150 people the recipe would need to be made 19 times over and require 38 pounds of potatoes.
I would use 40 pounds.
To feed 200 people with parsley potatoes, you generally estimate about 1/2 to 3/4 pound of potatoes per person, depending on whether it's a side dish or a main component. Therefore, you would need approximately 100 to 150 pounds of potatoes. Adjust the quantity based on the overall menu and portion sizes. Don't forget to account for the weight of any additional ingredients like parsley and seasoning.
The average Iowa farmer feeds about 150 people.
That is 37.5 pounds.
I'd say about 150-200 maybe?
I would use 150 cans
Are you CRAZZY wow why would you feed 150 peaople?!?!?!?!
At least 150, although some people will take two, so plan on 300. If there are leftovers there may be shelters in the area that will take a food donation.
50
I usually allow 4 ozs per person. This would be 37.5 pounds for 150 people
