Question

A certain forest covers an area of 2500 km^2.

. Suppose that each year this area decreases by 7%.
. What will the area be after 10 years?
round your answer to the nearest square kilometer.

Answer 1

1209.95 km^2

Explanation:

This can be represented as exponential decreasing function.

y = a(1 - r)t

a = starting amount

r = rate

t = years

y = 2500(1 - .07)^10

= 2500(.93)^10 = 1209.95

In 10 years, the forest will shrink in size to 1209.95 km^2
