Question

Forest covers an area of 3400 km^2. Each year this area decreases by 7.25%. What will the area be after 13 years

Answer 1

Area of 3400 decreases by 7.25%.

Rewrite 7.25% as a decimal.

This leads to 0.0725.

So, (3400)(0.0725) = 246.5.

Now (246.5)(13 years) = 3,276.

The area after 13 years will be

3,276 km^2.
