At the start of an experiment, there are 30 bacteria in a dish. the bacteria population is expected to grow at a rate of 180% each day. which is the best prediction for the bacteria population after 7 days?

Let At be the number of bacteria in the petri dish after t days. The equation that would best represent the given scenario in this item is,
                                    At = (Ao)(1.8^t)
Ao is equal to 30. Substituting the known values,
                                  At = (30)(1.8^7) = 1836.66 bacteria
Therefore, there are approximately 1837 bacteria after 7 days.
