: The population P of a certain culture is expected to be given by a model P=100e^rt where r is a constant to be determined and t is a number of days since the original population of 100 was established. Find the value of r if the population is expected to reach 200 in 3 days.
Thank you.

P = 100e^(rt)
200 = 100e^(3r)
ln(2) = 3r
ln(2)/3 = r
