The population of a city is 40,000 and the annual growth rate is 1.6%. Write an equation to model the population y after x years.

Y=40,000(1.016)^x

Explanation:

years= x

Predicted population= y

Initial population= 40000

you can find the population y after x years with the help of this function

For example:

If we want to know the population after 5 years, put x=5 and find y

Y after 5 years= 40000(1.016)^5

                      =43304

your answer would be 10x - 1
