Question:

 

3. The total profit function of a company is defined by P(x, y) = 8x+10y-x²+xy-2y²-10; where x & y stands for two types of goods. Define constraint optimization. Differentiate partially the function upto 2nd order and hence evaluate at (-2,3) If the company has a production quota x+y=10, determine how many units of each good should be produced and sold in order to maximize total profit and what is the maximum profit?
