Population of a city is 36000 in 2005 by 2010 it has grown to 43800. If the city has grown linearly since 2005 and grows at the same rate what will the population be in 2015



Answer :

36000 : 2005 = 43800 : 2010
Every five years it increases by 7800, so by 2015 it will be
43800 + 7800
= 51600

The population of the city in the year 2015 will be 51,600.

What is the rate of change?

The rate of change is the speed at which variable changes over a specific period of time.

The population of the city in the year 2005 = 36,000

The population of the city in the year 2010  = 43,800

The change in population in 5 years is given by;

= Population in the year 2010 - Population in the year 2005

= 43,800  - 36,000

= 7800

The change in population in 5 years = 7800

Let us assume the number population in the year 2015 = x

Here, according to the question:

Since the change of rate is a linear growth since 2005.

The change in population every 5 years  = 7800

The change in population in the next 5 years is;

Rate of change = Population in year 2015 - Population in the year 2010

7800 = x - 43,800

x = 7800 + 43800

x = 51,600

Hence, the population of the city in the year 2015 will be 51,600.
