Growth exponential

Question

The population of a city is increasing at a rate of 4% each year. In 2000, there were 236,000 people in the city.  Let t represent the number of years since 2000 and P represent the population. Write an exponential growth function to model this situation.

P=[ ] (1+ )^t

Answer 1

You already have the outline of the exponential growth equation. Just substitute the starting value in the year 2000 and the percent growth rate.

P = 236000(1 + .04)^t. Just needed to convert the percent to a decimal first.
