Okay, since there are 12,096 population in an are of 15 square miles in Brighton, and it is given that Pauling has 22.5 square miles with the same density, our equation will be like this:

Let x be the population of Pauling

12,096/15 = x/22.5

806.4=x/22.5

we multiply both sides by 22.5 and we get

18144 = x


Therefore, the population of Pauling is 18,144. :)
