To solve this problem what you should do is write an equation of the potential type.
We have then that the generic equation is:
y = A * (b) ^ t
Where,
y: number of bacteria after t hours.
A: initial population of bacteria.
b: growth rate of bacteria (b> 1)
t: time (in hours for this case).
Note: compare the given expression with the generic equation shown to find the answer.
