In a laboratory experiment, scientists are studying the growth of a newly discovered bacteria species, Bacterium rapidus, which thrives in warm, nutrient-rich environments. At the start of the experiment, the bacteria population is measured to be 500. The bacteria reproduce rapidly, and with a maximum per capita growth rate of 12% per hour. This is the population size of the bacteria after 8 hours.
Equation is N=N0ert
