In a certain country, the rate of deforestation is about 3.61% per year. Assume that the amount of forest remaining is given by the function

$F = F_0 e^{-0.0361 t}$

where $F_0$ is the present acreage of forest land and $t$ is the time in years from the present. In how many years will there be only 60% of the present acreage remaining?
Round your answer to three decimal places.

years from now
