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.
