Bacillus cereus is a soil-dwelling bacterium that sometimes causes food poisoning. Each cell divides to form two new cells every
Readme [11.4K]

Answer: There are 6400 bacteria that will be present after 3 hours.

Step-by-step explanation:

Since we have given that

Initial number of bacterial cells = 100

Each cell divides to form two new cells every 30 minutes.

Number of hours = 3 hrs

Number of minutes in 3 hours = 3\times 60 = 180 minutes

Number of 30 minutes in 3 hours = \dfrac{180}{30}=6

So, our equation becomes,

P(x)=ab^x\\\\P(3)=100(2)^6\\\\P(3)=6400

Hence, there are 6400 bacteria that will be present after 3 hours.
