have put together the math in words, please help me show the work in a math format. Info below Note 1,2,3
To find the population growth rate subtract the population of 2006 from 2007. Divide that answer by the 2006 population.
Australia’s growth rate from 2006 to 2007 was 0.67% per year.
1). 20,743,300 subtract 20,605,500 divided by 20,605,500 which equal the Population growth which is .00668 = 0.67%
2). 20,743,300 times .0067 equals the amount of growth of the population in 2007 which equals 138981
3). Find the approximate population which is 138981 + population of 2007 (which is 20,743,300) = 2008 population which is 20,882,281( 26 January 2008)
Using Australia data in the reference
20,882,281( 26 January 2008)
20,743,300 (26 January 2007)
20,605,500 (26 January 2006)
20,171,300 (26 January 2005)
I have responded to an earlier post of the same question.
To show the work in a math format, you can express the calculations as follows:
1) Population growth rate calculation:
Population growth rate = (Population of 2007 - Population of 2006) / Population of 2006
Population growth rate = (20,743,300 - 20,605,500) / 20,605,500
Population growth rate = 137,800 / 20,605,500
Population growth rate ≈ 0.00668
2) Amount of population growth in 2007:
Population growth in 2007 = Population of 2007 * Population growth rate
Population growth in 2007 = 20,743,300 * 0.00668
Population growth in 2007 ≈ 138,981
3) Approximate population of 2008:
Approximate population of 2008 = Population of 2007 + Population growth in 2007
Approximate population of 2008 = 20,743,300 + 138,981
Approximate population of 2008 = 20,882,281 (as of 26 January 2008)
Therefore, the approximate population of Australia in 2008 was 20,882,281.
