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 years? a. y = 8,500(0.12)x b. y = 1.12(8,500)x c. y = 8,500(1.12)x d. y = 12(85)x

C.

Step-by-step explanation:

The exponential equation with rate of growth r in time period x is given by :-

, where A is the initial value.

Given: The initial area of developed land A=  8,500 square miles

The rate of growth r= 12%=0.12

Now, the equation models the square mileage of developed land, y, after x years will be:
