A certain forest covers an area of

3600

km2

. Suppose that each year this area decreases by

8.5%

. What will the area be after

6

years?

Let:

P be the Initial Area, = (3500 km²)

r, the rate of decrease = ( - 8.5%)

n, the number of year = 6 years

A the resulting Area:?

A = P (1+i) ⁿ

A = 3600 (1-0.085) ⁶

A = 3600 (0.915) ⁶

A = 2112.66 km²
