The formula Pt = P0 * 2^(t/d) can be used to calculate the population of bacteria after t hours, where Pt is the population after t hours, P0 is the initial population, t is the time in hours, and d is the doubling time.
In this case, P0 = 8300 bacteria, t = 3 hours, and d = 10 hours.
So, Pt = 8300 * 2^(3/10) = 8300 * 2^(0.3)
To find the nearest whole number, we can round the answer up or down.
Using a calculator, we find that 2^(0.3) is approximately 1.344.
Therefore, Pt = 8300 * 1.344 = approximately 11,194 bacteria
So, the population of bacteria in the culture after 3 hours is approximately 11,194 bacteria, to the nearest whole number.
