Question

A colony of 30,000 bacteria doubles in size every 29 hours. what will the population be 58 hours from now

Answer 1

This is an example of exponential growth.

Since the population doubles in size every 29 hours,

and the initial population is 30000,

then in 29 hours,

the population = 30000 x 2 = 60000

and in

another 29 hours (total of 58 hours from the start),

the population = 60000 x 2 = 120000

Hence the population after 58 hours is 120000 bacteria.
