A microbiologist is observing the growth of a new strain of bacteria in a petri dish. The population can be modeled by the function [math]P(t)=P_0⋅2^(kt)[/math], where t is time in hours. At the start of the experiment (t=0), the population was 150 bacteria. After 2 hours, the population was measured to be 600 bacteria. If the food supply in the petri dish can only sustain a population of 25,000 bacteria, how many hours after the start of the experiment will the food be depleted?
- 7.4 hours
- 8.2 hours
- 9.1 hours
- 10.5 hours
