Explanation
Understanding the Problem We are given employment data for four professions in 2006 and 2016 and asked to determine which profession is projected to have the greatest percent increase in the number of jobs from 2006 to 2016.
Calculating Percent Increase To find the profession with the greatest percent increase, we need to calculate the percent increase for each profession using the formula: Percent Increase = 2006 Employment 2016 Employment − 2006 Employment × 100 Then, we compare the percent increases and identify the profession with the highest value.
Calculating Percentage Increase for Each Profession For Orthodontist: Percent Increase = 9206 10214 − 9206 × 100 = 9206 1008 × 100 ≈ 10.95% For Sound Engineer Technician: Percent Increase = 16125 17864 − 16125 × 100 = 16125 1739 × 100 ≈ 10.78% For Police Officer: Percent Increase = 648982 719041 − 648982 × 100 = 648982 70059 × 100 ≈ 10.80% For Editor: Percent Increase = 122273 124135 − 122273 × 100 = 122273 1862 × 100 ≈ 1.52%
Comparing Percentages and Identifying the Maximum Comparing the percent increases, we have: Orthodontist: approximately 10.95% Sound Engineer Technician: approximately 10.78% Police Officer: approximately 10.80% Editor: approximately 1.52% The Orthodontist profession has the highest percent increase.
Final Answer Therefore, the profession projected to have the greatest percent increase in the number of jobs from 2006 to 2016 is Orthodontist.
Examples
Understanding percentage increase is crucial in various real-world scenarios, such as tracking investment growth, analyzing sales trends, or monitoring population changes. For instance, if you invest $1,000 in a stock and it grows to $1,100 in a year, the percentage increase is (($1,100 - $1,000) / $1,000) * 100 = 10%. This concept helps you evaluate the performance of your investments and make informed financial decisions. Similarly, businesses use percentage increase to assess sales growth and identify areas for improvement, while governments use it to monitor population changes and plan for future needs.
The profession projected to have the greatest percent increase in jobs from 2006 to 2016 is Orthodontist, with an increase of approximately 10.95%. The other professions had lower percent increases. Thus, option A is the correct answer.
