Question

A town's population has been growing linearly. In 2003, the population was 66,600 people, and the population has been growing by approximately 2,400 people each year.Write the formula for the function  which represents the population of this town  years after 2003.

Use this function to determine the population of this town in the year 2014.

Answer 1

P(x) = 66,000 +2400t where t = number of years since 2003. for 2014, t = 11

P(11) = 66,000+2400(11) = 66000+26400= 92,400 in 2014
