A known constant for the initial population quantity is needed. Call this number, N. Let the population at any time x be p.

The period for population tripling is 1 hour, so if x is in hours,
highlight_green%28p=N%2A%283%29%5Ex%29----------your model.

After 5 hours, the value for p is very simply p=N%2A3%5E5 or p=243%2AN.
