Answer to Problem 33PPS
City | Population 2000 | Population 2006 | Amount of Change | % of Change |
Raleigh, NC | 276,093 | 356,321 | 80,228 | 29% |
Columbia, SC | 116,278 | 119,961 | 3683 | 3% |
Frankfort, KY | 27,741 | 27,077 | -664 | -2% |
Columbus, OH | 711,470 | 733,203 | 21733 | 3% |
Explanation of Solution
Given information : The population of capital cities for four different states
Formula used : Amount of Change= Population 2006-Population 2000
% of Change= Amount of Change/ Population 2000
Calculation : For Raleigh , NC:
Amount of Change
% of change
As the % is a positive number, thus it shows a population increase by 29%
Similarly,
For Columbia, SC Amount of Change
% of change
As the % is a positive number, thus it shows a population increase by 3%
For Frankfort, KY:
Amount of Change
(- shows the decrease in population)
% of change
As the % is a negative number, thus it shows a population decrease by 2%
For Columbus, OH:
Amount of Change
% of change
As the % is a positive number, thus it shows a population increase by 3%
b.
To state : Compare the amounts of change and the percent of change between the two cities and explain the differences and similarities between the two.
b.
Answer to Problem 33PPS
According to the calculated data, there is a lot of difference in amount of change of population as population of Columbus is very much greater than the population of Columbia.
Whereas, % of change (rounded to nearest whole number), is same of both the cities which shoes that the change in population in percentage in both the cities varies with same percentage.
Explanation of Solution
Given information : The population of capital cities for four different states
For Columbia, SC Amount of Change
% of change
For Columbus, OH:
Amount of Change
% of change
Amount of change of Columbia, SC is less than the amount of change of Columbus, OH
% of change of Columbia, SC is equal to the % of change of Columbus, OH
