It takes 21 minutes for a certain population of bacteria to double. If there are 8,014,627 bacteria in
this population at 10 a. m., what is the best estimate,
in millions, of the number of bacteria at 10:42 a. m.
on the same day?

32,058,508 bacteria at 10:42am

Step-by-step explanation:

10am: 8,014,627

10:21: 8,014,627 × 2 (doubled) = 16,029,254

10:42: 16,029,254 × 2 (doubled) = 32,058,508
