Question 61 - Math Practice Test for the SAT Exam

The bacterium E. coli divides about once every thirty minutes. If a culture of 500 of these bacteria has ideal conditions (abundant food, space to grow, safety from predators, etc.) and we neglect the possibility of death, which equation accurately predicts the population \(P\) as a function of time \(t\), measured in minutes?

\[P(t)=500^{30t}\]
\[P(t)=500×2^{30t}\]
\[P(t)=500^{\frac{t}{30}}\]
\[P(t)=500×2^{\frac{t}{30}}\]
