A colony of 1,000 bacteria doubles in size every 14 minutes. What will the population be 42 minutes from now?
bacteria

Nt = 2^n × No

Where Nt= No. Of cells at time t(for given time)

No= Initial no. Of cells (In your given case it's 10)

n = no. Of genarations

You can find ‘n' by using formula

n = t/g ….where g = generation time or doubling time for given bacteria .(in your given case it's 1 min.)

& t = given time
