A city has a population of 280,000 people. suppose that each year the population grows by 4.5% . what will the population be aft

Anastasy [175]

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 :

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

Where P= starting population = 280000

r= rate of growth = 0.45

t= time = 15

now plug these values into above formula.

$A=280000(1+0.45)^{15}$

$A=280000(1.45)^{15}$

$A=280000(263.34194176)$

$A=73735743.6928$

Hence population after 15 years will be approx 73735743.

$500 x 0.85 = 425
$425 x 0.85 = 361.25
$361.25 x 0.85 = 307.10
$307.1 x 0.85 = 261
$261 x 0.85 = 221.85
