Answer:

The population of this city in 10 years is 118,4160.

Explanation:

Given:

Suppose a city with population of 800,000 has been growing at a rate of 4​% per year.

If this rate​ continues.

Now, to find the population of this city in 10 years.

Let the population after growth be
A.

Original population (
P) = 800,000.

Growing rate per year (
r) = 4%.

Number of years (
t) = 10 years.

Now, we put formula to get the population of the city in 10 years:


A=P(1+r)^t


A=800,000(1+4\%)^(10)


A=800,000(1+0.04)^(10)\\\\A=800,000(1.04)^(10)\\\\A=800,000* 1.4802\\\\A=118,4160.

Therefore, the population of this city in 10 years is 118,4160.
