Question 1091383
-----------------------------------------------------------------------------
population of Guatemala in 2000 was 12.7 million. Assuming exponential growth, what would be the size of the population after time t (measured in years after 2000) if the population was 15 million in 2020? 
-----------------------------------------------------------------------------


{{{y=p*e^(kt)}}}
-
{{{15=12.7*e^(k*20)}}}, because {{{t=2020-2000=20}}};
{{{e^(20k)=15/12.7}}}
{{{e^(20k)=1.1811}}}
{{{20k=ln(1.1811)}}}
{{{k=ln(1.1811)/20}}}
{{{k=0.00832}}}
