A culture of a certain bacteria doubles every hour. At 9:00 a.m, there were already 120 bacteria. Which equation represents the number of bacteria, n , at 8:00 a.m? How many bacteria were there?(1 point)

Answer 1

The equation that represents the number of bacteria, n, at 8:00 a.m can be written as:

n = 120 / 2

Simplifying this equation gives:

n = 60

Therefore, there were 60 bacteria at 8:00 a.m.
