FILL IN THE BLANK. A company manufactures two products, A and B. If x is the number of thousands of units of A and y is the number of thousands of units of B, then the total cost and total revenue in thousands of dollars are C(x, y) = 2x² - 2xy + y² - 10x - 7y + 11 R(x, y) = 8x + 7y. Find the number of each type of product that should be manufactured to maximize profit. (Assume that profit will be maximized at its critical point.) x = ______ thousand uunits
y = ______ thousand units
What is the maximum profit?_____ thousand dollars
