Question

Start with 4 bacteria, growing by a factor of 3 every hour. After 3 hours, how many bacteria will there be?

A) 36
B) 81
C) 108
D) 243

Answer 1

The number of bacteria after 3 hours with a growth factor of 3 is 108.

Step-by-step explanation:

To calculate the number of bacteria after 3 hours, we need to find the result of multiplying the initial quantity of bacteria by the growth factor raised to the power of the number of hours. In this case, the initial quantity is 4 bacteria and the growth factor is 3. So, after 3 hours, the number of bacteria will be 4 * (3^3) = 4 * 27 = 108.

Therefore, the correct answer is option C) 108.
