Iwould say about, 3; depends on the person though...
A 7.5 pound turkey breast is not enough to feed 11 people. An 11 pound turkey would be enough to feed 11 adults.
A 6.5 pound turkey will feed 6 adults. The rule with turkey, is there should be 1 lb. of turkey for every adult.
A person should have at least 1 20 pound turkey and 1 10 pound turkey in order to feed 20 people. There should be 1 pound of turkey for each person.

To estimate how many 12-pound turkeys you would need to feed 300 people, a general guideline is to allocate about 1 to 1.5 pounds of turkey per person. For 300 people, you would need approximately 300 to 450 pounds of turkey. Dividing this by the weight of each turkey (12 pounds), you would need about 25 to 38 turkeys to adequately feed that number of guests. Therefore, around 30 turkeys would likely be a good estimate for 300 people.
What size bird should I buy?It depends on how many people you will be serving, and how big a bird your oven can hold. A larger turkey is more efficient at producing meat. For instance, turkeys weighing less than 12 pounds will serve 1 person for each pound of weight. A 10-pound bird will serve 10 people. But a turkey weighing more than 12 pounds will feed 1 guest for each 3/4 pound of turkey weight. So, if you're having 20 guests, you'll only need a 15-pound bird.
A 10 lb turkey can typically feed around 6-8 people.
That will feed approximately 120 people.
