The owner of a mid-size company advertises on the television and on the radio. He has found that the number of units that he sells is approximated by N(x, y) = -0.5x2 - 0.9y2 + 13x + 18y + 350, where x (in thousands of dollars) is the amount spent on television advertising and y (in thousands of dollars) is the amount spent on radio advertising. How much should he spend on each to maximize the number of units sold?
