How much should the chemist buy from each supplier to minimize the cost of her purchase>>
buy the required 7 tons from A, zero from B. That minimizes the cost.
Wouldn't it be wonderful if problems asked what they really wanted?
A chemist wants to mix two kinds of glycerins for the manufacture of a soap. The glycerin from supplier A cost $1 million per ton and the glycerin from supplier B costs $1.5 million per ton. The chemist is obligated to buy no more than twice as much glycerin from supplier B as she does from supplier A. Furthermore, the chemist must buy at least 7 tons but no more than 9 tons from supplier A. How much should the chemist buy from each supplier to minimize the cost of her purchase.
