In 2007 the population of Pakistan was 164 million, and it is expected to be 205 million in 2025.
a) Approximate C and also a so that P(x) = Ca^x-2007 models these data, where P is in millions and x is the year.
b) Estimate the population of Pakistan in 2015, and compare your estimate to the predicted value of 204 million.
c) Estimate when this population could reach 212 million.
