Suppose that the number of bacteria in a certain population increases according to a continuous exponential growth model. A sample of 1900
bacteria selected from this population reached the size of 2116
bacteria in five hours. Find the hourly growth rate parameter.

campbell_st · Answer

so the model is 

$$A = P \times e^{kt}$$

A is the future population, P is the initial population, k is the growth contant and t is the time in hours.

is that what you are using..?

anonymous · Answer

So set it up as 

2116=1900*e^k*5

and solve for k?
