Suppose you ingest 40 cells of Salmonella typhimurium in a chicken taco. Some of the bacteria are killed as they pass through the stomach but 20 viable cells survive and reach the intestine. Suppose further that Salmonella generation time in the intestine is 2.5 hours and that you will feel sick when there are 1,000,000 bacteria in your gut . How much time will elapse before you feel sick? Show your work.
