Maximum Price of Land The rectangular region R shown in the accompanying figure represents the financial district of a city. The price of land within the district is approximated by the function (x, y) = p(x, y) = 230 15 15(x - 2)² - 10(y - 3)². where p(x, y) is the price of land at the point (x, y) in dollars per square foot and x and y are measured in miles. At what point within the financial district is the price of land highest? 2 y (miles) 10 000 000 000 R N. 2 →x (miles)
