Question

A certain forest covers an area of 3900 km^2. Suppose that each year this area decreases by 6.75%. What will the area be after 12 years

Answer 1

1686

Explanation:

Rate of reduction = 100 - 6.75 = 93.25%

After 12 years, the reduction in trees = 0.9325^12 = 0.432301

Area after 12 years = 3900 x 0.432301 = 1686
