The number of bacteria in a culture is increasing according to the law of exponential growth. The initial population is 240 bacteria, and the population after 12 hours is double the population after 1 hour. How many bacteria will there be after 3 hours

240

Step-by-step explanation:

According to law of exponential growth,

Here, denotes the initial amount and k is the rate constant of the equation.

Now, the initial population is 240 bacteria.

Put

So,

The population after 12 hours is double the population after 1 hour.

(Formulae used: )

So,

Therefore,

Number of bacteria after 3 hours = 240
