To prevent bacterial infections, it is recommended that you wash your hands and cooking utensils as often as possible. At a family barbeque, Jim prepares his meat without using proper sanitary precautions. There are about 130 colony-forming units (CFU/mL) of a certain type of bacteria on the meat. Harold prepares his meat using proper sanitary precautions, so there are only 5 CFU/mL of the bacteria on his meat. It is known that the doubling time for this type of bacteria is 20 minutes. (a) For each situation, find an exponential model for the number of bacteria on the meat thours since it was prepared. fjim(0 fHarold(t) (b) For each model, find the predicted number of bacteria after 6 hours. (Round your answers to two decimal places.) fJim(6) = hundred thousand CFU/mL fHarold(6) = hundred thousand CFU/mL To prevent bacterial infections, it is recommended that you wash your hands and cooking utensils as often as possible.
