Question

Adam is going to cook a turkey for 14 peopleand wants to allow 3/4 lb per person.

Answer 1

Wonderful!  You've given us a veritable wealth of data to play with,
including the size of the guest list, the meat ration for each turkey,
and a useful metric to English conversion.

Now, if you had only told us something about the unit price of
the birds, we might even be able to answer the question that
you actually asked.
