The population density of a city is given by P(x,y)= -25x²-20y² + 200x+600y + 180, where x and y are miles from the southwest corner of the city limits and P is the number of people per square mile. Find the maximum population density, and specify where it occurs. The maximum density is people per square mile at (x,y)=
