A culture of a certain bacteria doubles every hour At 9:00 am, there were already 120 bacteria. Which equation represents the number of bacteria, m, at 8:00 am? How many bacteria were there? (1 point)
2n = 120 at 8:00 am, there were 240 bacter
2n = 120 at 6:00 am, there were 60 bacteria
pi/2 = 120 at 8:00 am, there were 240 bacteria
pi/2 = 120 at 6:00 am, there were 60 bacter
The correct answer is:
2n = 120 at 8:00 am, there were 240 bacteria.
