Question

suppose that one bacterial cell divides every 30 minutes to make 2 cells. write an expression to find how many cells there will be after 3 hours. then solve to find the total number of cells after 3 hours.

Answer 1

with time in hours, starting with one cell, after t hours, the population p will be

p(t) = 2^(2t)
p(3) = 2^6 = 64

Answer 2

12 cells
