<pre>

As described in the problem, the growth is an exponential function.


The multiplicative growth coefficient in 8 years is  {{{120000/50000}}} = {{{12/5}}} = 2.4.


The 16-years time period is twice 8-years period.


If the multiplicative growth rate remains the same, then after 16 years the number of bacteria will be


    {{{50000*(12/5)*(12/5)}}} = {{{50000*2.4^2}}} = 288000.     <U>ANSWER</U>
