The population of Smallville increased by 20% from 2000 to 2005 and it increased by 30% from 2005 to 2010. By what percent did the population of Smallville increase from 2000 to 2010?

Percentage increase in population of Smallville from 2000 to 2010 is 56%

Step-by-step explanation:

The population of Smallville increased by 20% from 2000 to 2005. Let assume that the initial population in 2000 = P

Increased value = (100 +20)/100 × P

Increased value = 120/100 ×P

Increased population = 1.2P

and it increased by 30% from 2005 to 2010.

Increased population= 130/100×1.2P

Increase population = 1.3 × 1.2P

Population = 1.56P

By what percent did the population of Smallville increase from 2000 to 2010

%increase = increase/initial × 100

Increase population = 1.56P - P

= 0.56P

Initial population = P

%Increase = 0.56P/P × 100

%increase = 0.56 × 100 = 56%

the answer would be 150 books
