A culture of bacteria has an initial population of 980 bacteria and doubles every 9 hours. Using the formula Pt = Po · 2 t/d, 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 13 hours, to the nearest whole number?​
