A culture of bacteria has an initial population of 200 bacteria and doubles every 5 hours. Using the formula P4 = Po . 28, where Pt 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 4 hours, to the nearest whole number?
