Question

A country's population in 1992 was 103 million. in 1997 in was 108 million. estimate the population in 2004 using the exponential growth formula. round your answer to the nearest millionth. P=Ae^kt

Answer 1

108=103e^(5k)

108/103=e^(5k)  take the natural log of both sides

ln(108/103)=5k

k=ln(108/103)/5

k≈0.00948

P=103e^(12*0.00948)

P≈115 million (to nearest million)
