A culture of the bacterium Salmonella enteritidis initially contains 50 cells. When introduced into a nutrient broth, the culture grows at a rate proportional to its size. After 1.5 hours, the population has increased to 975. (a) Find an expression for the number of bacteria after t hours. Thus the number of bacteria after 3 hours. After how many hours will the population reach 250, 000 ?
