that's if it doesn't have to be in percentage form
Answer:
![y= 250000(1.022)^x](https://tex.z-dn.net/?f=y%3D%20250000%281.022%29%5Ex)
Step-by-step explanation:
The population of a city is 250,000 and the annual growth rate is 2.2%
General equation for exponential growth is
![y= P(1+r)^x](https://tex.z-dn.net/?f=y%3D%20P%281%2Br%29%5Ex)
Where y is final population and P is the initial population
'r' is the rate of growth and x is the number of years
p = 25000 and r= 2.2%= 0.022. Replace all the values in the general equaiton
![y= P(1+r)^x](https://tex.z-dn.net/?f=y%3D%20P%281%2Br%29%5Ex)
![y= 250000(1.022)^x](https://tex.z-dn.net/?f=y%3D%20250000%281.022%29%5Ex)
