Answer :

Let initial bacteria, P0=10000.

A colony of 10,000 bacteria doubles in size every 29 hours.

So, in first 29 hours, the bacteria becomes 20000.

In the next 29 hours, the bacteria becomes 40000.

[tex]20000\times2=40000[/tex]

Now, 29+29=58 hours.

In the next 29 hours, the bacteria becomes

[tex]40000\times2=80000[/tex]

Now, the total hours is 58+29=87 hours.

So, in 87 hours the bacteria becomes 80000.
