The formula for that represent the area covered by a marsh A(n) is .
An exponential decay is given by the function:
y = abˣ
Where a is the initial value of y, b is a constant which is less than 1, y, x are variables.
Since the area covered by a marsh, A, starts at 11500 acres, hence a = 11500. Since the area drops by 1/4 each year for n years, hence:
Therefore the formula for A(n) is
