Due to an increasing population, developed land in a region is increasing at a rate of 12% per year. if there are currently 8,500 square miles of developed land, which equation models the square mileage of developed land, y, after x year?

Step-by-step explanation:

Since the population keeps increasing as the land keeps being developed we can assume that the rate of growth is compounded annually. That being the case we can use the Exponential Growth Formula to solve this problem. The Formula would be the following,

Where :

Since we were given the rate and the initial area of land we can plug it into the equation .

So with this formula we can calculate the amount of developed land after x years.
