Find the maximum value and the minimum value of the function and the values of x and y for which they occur. P = 20x - 4y + 66, subject to 7x + 8y $ 56, 0sys5, and OSX$7. The maximum value of the function is and it occurs where x = and y = The minimum value of the function is and it occurs where x = and y = (Do not round until the final answer. Then round to two decimal places as needed.)
