Question

A city has a population of 270,000

people. Suppose that each year the population grows by 6%

. What will the population be after 13

years? 

Use the calculator provided and round your answer to the nearest whole number.

Answer 1

Rose,

 

The population is 270,000 and grows by 6% every year

 

After 1 year the population will be 270,000*(1+6/100) = 270,000*1.06

 

After 2 years the population will be 270,000*(1.06)^2

 

So after 13 years the population will be 270,000*(1.06)^13 = 575890.6 or 575891
