Question

A certain forest covers an area of 4500 km². Suppose that each year this area decreases by 6.75%. What will the area be after 5 years?

Use the calculator provided and round your answer to the nearest square kilometer.

Answer 1

The area of the forest after 5 years will be of aproximately 3173km²

-The formula for the given problem is the following:

`4500(1-.0675)^(5)=y\\`

-If you solve for y the answer should be:

`y=3172.9024217`

-And since the problem is asking us to round it to the nearest square kilometer, we are going to round it to 3173km².
