I'm a bit confused with this math question. I just can't seem to get it, I would appreciate if any of you could help me out :)

 

A group of yeast cells doubles every 4 h. There is a population of 100 at 10 a.m. Write the function that models the growth of the population. Determine the population at 5 p.m.

P  = Po * 2^(n / 4)    

 

Where Po is the original population and P is the final population after n hours

 

So  our function is

 

P  = 100 * 2^(n /4)     and n  =   7   hours after 10AM  = 5PM

 

So

 

P = 100* 2^(7/4)   ≈  336
