Question

A population of fruit flies grows exponentially. At the beginning of the experiment, the population size is 100. After 18 hours, the population size is 117. a) Find the doubling time for this population of fruit flies. (Round your answer to the nearest tenth of an hour.) b) After how many hours will the population size reach 150? (Round your answer to the nearest tenth of an hour.)
