Under ideal laboratory conditions the rate of growth of bacteria is proportional to the size of the population at time tt. Suppose that 21002100 bacteria are present initially and that 42004200 are present 1 hour later. How many bacteria are there at the end of 55 hours?

The amount of bacteria that are there at the end of 55 hours is 2310231000

Explanation:

From the description in the question, the bacteria's population size doubles per hour;

Within 1 hour = 21002100 × 2 = 42004200

Thus

After 1 hr ⇒ 42004200

55 hrs ⇒ ?

? = 55 × 42004200 = 2310231000

The amount of bacteria that are there at the end of 55 hours is 2310231000
