You can put this solution on YOUR website!
Factor of 2, because "double" every three hours;

x hours,
y population at any x,
p initial population,
highlight%28y=p%2A2%5E%28x%2F3%29%29.

for some constant k, x=3 means k%2A3=1 period, k=1%2F3; so you want your exponent to be x%2F3. This would be the only part needing great care.

Now, you can simply evaluate y for x=24 and p=n.
y=n%2A2%5E%2824%2F3%29=n%2A2%5E8
