Exponential Decay Model

Question

a city had a declining population from 1992 to 1998. The population in 1992 was 200,000. Each year for 6 years, the population declined by 3%. Write an exponential decay model to represent this situation.

Answer 1

P(t)= 200000·0.97^t, where t is number of years from 2002, so in 208 t = 2008 - 2002 = 6 years
