The number of bacteria in a certain culture doubled every hour. If there were 30 bacteria present in the culture initially, how many bacteria will be present at the end of the 8th hour?
The number of bacteria after will be
Given the initially 30 bacteria present in the culture.
Also, the number of bacteria got doubled every hour.
So, using the equation
Where is number of bacteria after hours.
is bacteria present initially.
is the common ration, in our problem it is given that bacteria doubles every hour. So,
And is the number of hours. In our problem we need amount of bacteria at the end of hours. So,
Plugging values in the formula we get,
So, number of bacteria after will be
