A culture of bacteria has an initial population of 450 bacteria and doubles every 4

hours. Using the formula P+ = Po – 2a, where Pț is the population after t hours, Po
is the initial population, t is the time in hours and d is the doubling time, what is the
population of bacteria in the culture after 3 hours, to the nearest whole number?
