Question

A population of a city is 422,000 and increases by 12% each year. Use an exponential function to

find the population of the city after 8 years.

Answer 1

The population of the city after 8 years will be 1,044,856.

Explanation:

Person above me is correct

Answer 2

1,044,856

Explanation:

To solve this problem, we can use the exponential growth formula which is:

`A = P(1+r)^t`

A = total amount

P = original amount

r = growth rate (decimal)

t = years

Before we plug in the values, don't forget to change 12% to its decimal form.

12% ->
`(12)/(100)` -> 0.12

Now, lets plug in the values:

`A=422,000(1+0.12)^8`

`A=1,044,856`

The population of the city after 8 years will be 1,044,856.
