Janelle conducted an experiment by mistake when she left her bologna sandwich at school over winter break. When she got back, her sandwich was much larger than it was when she left it. Her science teacher explained that the sandwich had produced large quantities of a rare bacterium, Bolognicus sandwichae. Based on a sample taken from the sandwich, Janelle determined that there were approximately 72 million bacteria present. Her science teacher explained that this is not very surprising, since the number of this bacteria triples every 24 hours. Since the sandwich had been made only 15 days ago, Janelle was sure that she could sue the meat company. The food industry standard for the most bacteria a sandwich-sized portion can have at the time of production is 100. Find out how many of the bacteria were present when the sandwich was made to determine if Janelle has a case.
