During the exponential phase, E. coli bacteria in a culture grown continuously. If the growth rate is 2.8% per minute and the current population is 124.0 million, what will the population be 6.3 minutes from now?

~~1.479*10^8

Explanation:

We can equate it this way:
"Population"="constant" * e^("growth rate"*"time since")

At current time, t_0:
124000000="constant" * e^(0.028*0)
"constant"=124000000/1=124000000

Hence, at t=6.3,
Pop_(t=6.3)=124000000*e^(0.028*6.3)~~1.479*10^8
