Answer:
The population of the city in 2020 is 3,839,832
Step-by-step explanation:
Given:
Population at 2000 = 315,000
Rate at which the population increases = 2%
To Find:
The Population in the city after 2020 = ?
Solution:
The population in the city after 2020 can be found by using Exponential growth function.
Exponential growth occurs when a quantity increases by the same factor
Exponential growth function is 
Where
y is the final amount
a is the initial amount
r is the rate of increase
t is the time period.
Now substituting the values ,
In 2020 i.e., after 10 years





y = 3,839,832.42
Answer:
