Reed Bradford · Answer 1

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.
