Using this growth rate, if a person eats a meal with 8 E. coli bacteria, how many bacteria will be in the person after 12 hours? (Assume all bacteria survive and no antibiotics are taken). Use at least 5 digits in your calculations and report your answer to 2 significant digits. Stats source: http://textbookofbacteriology.net/growth_3.html.
