As before, recall that the number of bacteria afterDdoubling periods is given by the following, wherep(0)

is the initial population.

p(D) = 2^Dp(0)

We are given that the culture starts with800bacteria, and we previously determined that there are 2tdoubling periods inthours. Applying these values gives the following result.

p(D)=2^Dp(0)

p(2t)=

Therefore, how many bacteria are there afterthours?
