One textbook on linear algebra describres the Cambridge diet. In particularly, the book says: "In fact, the manufacturer of the Cambridge diet was able to supply 31 nutrients in precise amounts using only 33 ingredients". Prove that the manufacturer could have supplied the same 31 nutrients in precise amounts using only 31 or fewer ingredients.
