A scientist observes a population of bacteria in a petri dish. The population grows exponentially, doubling every 2hours. After 4hours of observation, there are about 6,000 bacteria.

Which equation can you use to estimate n, the number of bacteria that were originally in the petri dish?

The equation that can be used to estimate n, the number of bacteria that were originally in the petri dish, is:

n = 6000 / 2^2

n = 6000 / 4

n = 1500

Therefore, the estimated number of bacteria originally in the petri dish is 1500.
