Answer:
The size of the sample after four hours is of 3158 bacteria.
Step-by-step explanation:
The population after t hours can be modeled by the continuous exponential growth model, which is:

In which P(0) is the initial population and r is the growth rate paremeter.
A growth rate parameter of 17% per hour.
This means that 
Suppose also that a sample culture of 1600 is obtained from this population.
This means that 
Find the size of the sample after four hours.
This is P(4).




Rounding to the nearest integer
The size of the sample after four hours is of 3158 bacteria.
