Question

A country's population in 1993 was 72 million. In 1996 it was 76 million. Estimate the population in 2003 using exponential growth.

Answer 1

\[x _{0}\times e ^{kt}\] wherein \[x _{0}\] is the original population, k is the rate of change, t is time (usually in years), and e is the constant "e". :)

Answer 2

Use that formula, comparing 1996 to 1993 to find "k". Then plug that in for 2003, based time and original population off the 1996 numbers.
