Answer:
The answer to your question is: after two hours there will be 6400 cell/ ml
Explanation:
Data
Bacteria t = 0; 400 cells/ml
generation time = 30 minutes
# cells after two hours = ?
                                  # of bacteria               time
                                      400                            0
                                       800                         30 min
                                    1600                           60 min
                                    3200                           90 min
                                    6400                          120 min
