Question 1073461
Can you please help me solve this problem? In a country, deforestation occurs at the rate of about 4.1% per year. Assume that the amount of forest remaining is determined by the function {{{ F = Fo * e ^(-0.041t) }}}, where Fo 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? Hint: Find the amount of time it takes for Fo to become 0.06Fo. I'm not sure how to start this problem off. 
===================================================

So yes, that is close, except 60% is 0.60 (not 0.06).

{{{ F = 0.60Fo = Fo*e^(-0.041t) }}}
{{{       0.60 = e^(-0.041t) }}}      
{{{   ln(0.60) = -0.041t }}}

You'll just need to solve for t from here...
