It depends on how much nutrition and food those 9 people each need to survive.
If you're trying to determine how big of a turkey to buy for Thanksgiving, a good rule of thumb is to buy 1 pound of turkey per person to allow for seconds and leftovers. So if you're having 9 guests for Thanksgiving, you'll need a 9-pound bird.
edit:
Remember that a 9 pound turkey is not 9lbs of meat...you'll need to account for bones and wingtips, etc. Ideally for nine people, you'll want a 15lb bird.
3 pounds
Depends on the size. If its about 25 lbs you need 2 turkeys.
I just read on this site that the rule of thumb is 2 persons less than the number of pounds of turkey. As an example a 14 lb Turkey should feed 12 people. To verify this answer enter the question: How many people will a 15 lb turkey feed. GMac
A 7.5 pound turkey breast is not enough to feed 11 people. An 11 pound turkey would be enough to feed 11 adults.
You will need at least 25 pounds of turkey. You may need up to 50 pounds of turkey to feed 25 people depending on their appetite.
An 18-pound turkey will feed quite a few people. 18 pounds should feed about 12 people, with other side dishes being served.
A 5.5 kg turkey should feed about 12 people. A 5.5 kg turkey weight about 12 pounds, and there should be a pound per person.
A 6.5 pound turkey will feed 6 adults. The rule with turkey, is there should be 1 lb. of turkey for every adult.
There should be about 100 pounds of turkey for 100 people. There should be a pound of turkey for each person.
how many pounds of menudo to feed 10 people.
Allow about a half pound per person. That means you would need about 25 pounds to feed 50 people.
Ten to fifteen.
