Question 1100702
<br>
Here is a simplification of the "alternative" method shown by the other tutor....<br>
The population increases by a factor of 4 every 3 years.<br>
So the population after 10 years will be the original population, multiplied by 4 (10/3) times:
{{{400(4^(10/3)) = 40673}}}  to the nearest whole number.
