Answer:

[tex]y= 250000(1.022)^x[/tex]

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

[tex]y= P(1+r)^x[/tex]

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

[tex]y= P(1+r)^x[/tex]

[tex]y= 250000(1.022)^x[/tex]
