Answer

There would be 800 bacteria after 3 hours

Step-by-step solution

3 steps

To determine how many bacteria would be present after 3 hours, we need to know the initial number of bacteria and the growth rate. Assuming we have:

  • Initial number of bacteria (N₀) = 100
  • Growth rate (r) = 2 (doubling every hour)

The formula for bacterial growth is:

N = N₀ × 2^(t)

where:

  • N is the final number of bacteria
  • N₀ is the initial number of bacteria
  • t is the time in hours

  1. Substitute the values into the formula.

    N = 100 × 2^(3)

  2. Calculate 2^(3).

    2^(3) = 8

  3. Multiply by the initial number of bacteria.

    N = 100 × 8 = 800

    Final answer: There would be 800 bacteria after 3 hours.
