6) The annual profits (in millions) of a company are given by: B(x, y) = -x² - y² + 22x + 18y - 102, Where "x" is the amount invested in research (in millions) and "Y" is the spending on advertising (also in millions).

a) Find the benefits when and when x = 10, y = 8 and when x = 12, y = 10.

b) Find the values ??of x, y that maximize profit, along with the corresponding profit x y.
