Explanation:

Part A:

So we know that the bacteria doubles every (30) minutes.

2000 times 2 equals 4000 (30 minutes)

4000 times 2 equals 8000 (1 hour)

Answer for Part A:

8000 bacteria

Part B:

Now we do this function 2000(2)^14 (30 minutes long)

Answer to Part B:

I believe the answer is 32,768,000 (Please correct me if I'm wrong)
