Question

The population of a small town was 10,800 in 2002. Since then the population has decreased at a rate of 2.5% each year. Write an exponential function to model the situation then find the population of 2020

Answer 1

Answer:

See below

Step-by-step explanation:

A 2.5 % decrease means  97.5 % remains (.975)

population =  10800 ( .975) ^n     where n = years past 2002

  in 2020    n = 18

    10800 (.975)^18 = 6847  people
