Question

A certain forest covers an area of 4200 km2 Suppose That each year decreases by 8%. Wha will the area be after 15 years

Answer 1

Depreciation formula:

Total = starting value x (1 - percentage)^time

Total = 4200 x (1-0.08)^15

Total = 4200 x 0.92^15

Total = 1202.449 km^2

Rounded to nearest km = 1202 km^2
