# Acity has a population of 280,000 people. suppose that each year the population grows by 4.5% . what will the population

###### Question:

## Answers

Given that population of the city is 280000.

Rate of growth of the population = r = 4.5% = 0.045

We have to find population after 15 years so time

t = 15

We can use growth formula to find the required population which is given by :

[tex]A=P(1+r)^t[/tex]

Where P= starting population = 280000

r= rate of growth = 0.45

t= time = 15

now plug these values into above formula.

[tex]A=280000(1+0.45)^{15}[/tex]

[tex]A=280000(1.45)^{15}[/tex]

[tex]A=280000(263.34194176)[/tex]

[tex]A=73735743.6928[/tex]

Hence population after 15 years will be approx 73735743.

Step-by-step explanation:

A population of 280,000 growing at a constant rate of 5.5% will almost double in 12 years ( 72/5.5=13).

Step-by-step explanation:

Population= 280000 people

Population growth rate= 8.5%

Population growth in a year=

{(100+8.5)÷100} × 280000 =303800 people

Pop growth in 8 years =

303800×8=

2,430,400 people
