A certain forest covers an area of 3700 km. Suppose that each year this area decreases by 5.5%. What will the area be after 15 y
Bess [88]

Answer:

1584 square kilometers.

Step-by-step explanation:

Here's the function I use.

y=a(1-r)^t

a= starting amount

r= rate

t= years

First step: y=3700(1-0.055)^1^5

Second step: =3700(0.945)^1^5

Third step: =1583.72164269

Fourth step: Round to the nearest square kilometer. Since 1583.7 is closer to 1584, you must round up.

Fifth step: The final answer is 1584 km^2

Hope this helps and stay during these crucial times. We'll get through this!
