Question 1006436
p for population
t for count of months


Exponential growth model, {{{p=2*3^t}}}


You can plug in successive values for t and plot points and read from the graph, or you can try:
{{{log((p))=log((2))+log((3^t))}}}
{{{log((p))=log((2))+t*log((3))}}}
{{{log((p))-log((2))+t*log((3))}}}
{{{log((p/2))(1/log((3)))=t}}}
and now p=500.
{{{t=log((500/2))/log((3))}}}
{{{highlight(t=log((250))/log((3)))}}}
