Answer:
(d) 24,057
Explanation:
Starting with 11 bacteria in a culture that triples in size every hour, you want to know the number grown in the 7th hour.
Exponential function
In hour 0, we have 11, and the growth factor per hour is 3. That means the population can be modeled by ...
p = 11·3^t
where t is in hours.
In the 7th hour, the population will grow to 11·3^7 = 24,057.
