 Question 107575: It is estimated that at the present rate of deforestation in El Salvador, in 20 years only 53% of the present forest will remain. How long will it take to remove 95% of the forest?Answer by josmiceli(9697)   (Show Source): You can put this solution on YOUR website!I'm assuming this is a linear relation with a negative slope. I want the vertical axis to be p = percent of present forest remaining The horizontal axis is years from the present The points given are P1 = (20,.53) P2 = (x,.05) note that 95% removed leaves 5% left Also I have the p-intercept (0,1) where 0 represents the present The equation is note that when x=0, p = 1 The slope is The question is, when p = .05, what is x? years answerThis is about 40 y 5 m 5 d
