A certain forest covers an area of 2600 km2. Suppose that each year this area decreases by 7.75%. What will the area be like after 15 years?

After 15 years, the area will be of 775.3 km²

Step-by-step explanation:

The equation for the area of the forest after t years has the following format.

In which A(0) is the initial area and r is the yearly decrease rate.

A certain forest covers an area of 2600 km2.

This means that

Suppose that each year this area decreases by 7.75%.

This means that

So

What will the area be like after 15 years?

This is

After 15 years, the area will be of 775.3 km²

step-by-step explanation:

32.50-7.50=25

225/25=11
