Solve for k . a country’s population in 1993 was 107 million . in 1999 it was 112 million . estimate the population in 2017 using the exponential growth formula. round your answer to the nearest million. p=ae^kt.

Using the given numbers, you can write the exponential function as
  P = 107*(112/107)^(t/6)
where t = years since 1993.

This can be written in the form
  P = 107*e^(kt)
where
  k = ln(112/107)/6
  k ≈ 0.00761167 . . . . . . . your value of k

The population in 2017 by this model is
  107*e^(0.00761167*(2017 -1993)) ≈ 128.446

The growth formula estimates the 2017 population at 128 million.
