A business produces two products brands, the quantities of which are xand J. The Business can produce a total of 44 items daily. The profit function of the business is n(x, y) = 30x - 3x2 + 5xy - 2y2 + 10y Find the maximum daily profit for the firm. The Lagrange function is a. L(x, y, A) = 30x - 3x2 + 5xy - 2y2 + 10y +A(x+ y-44) b. L(x, y, A) = 30x - 3x2 +5xy - 2y2 + 10y + 441 c. L(x, y, A) = 30x - 3x2 + 5xy - 2y2 + 10y + 1(x + y) d. L(x, y, A) = 30x - 3x2 + 5xy - 2y2 + 10y + A(x -y -44)
