Question

A town has a population of 12000 and grows at 3.5% every year. What will be the population after 7 years, to the nearest whole number?

Answer 1

Answer:

After 7 years the population will be 15268.

Step-by-step explanation:

Given a town has a population of 12000 and grows at 3.5% every year. we have to find the population after 7 years.

As the general growth formula is

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

where A = Amount after growth

           P = Original amount

           r = yearly growth rate

           t = no. of years

here, P=12000, r=0.035, t=7

$A=12000(1+0.035)^7$

         =$12000(1.035)^7$

        = $15267.35\sim15268$

Hence, after 7 years the population will be 15268.
