Question

A certain forest covers an area of 2600 km". Suppose that each year this area decreases by 4.5%. What will the area be
after 15 years?

Answer 1

Answer:

1300 km²

Step-by-step explanation:

A = P(1 + r)^t

where A is the final amount,

P is the initial amount,

r is the rate,

and t is time.

Given P = 2600, r = -0.045, and t = 15.

A = 2600 (1 − 0.045)^15

A = 1303.2

Rounded, the area decreases to approximately 1300 km².
