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?
