Explanation
The image shows a pie chart showing the population percentages in Florida in 2013 by age. In this graph there are 5 main groups: Dark blue color that represents the population of 19 years or less, which corresponds to 23.5%; yellow color represents the population from 20 to 39 years old, which corresponds to 25.1%; green color represents the population from 40 to 59 years old, which corresponds to 27.5%; The red color represents the population aged 60 to 79, which corresponds to 18.8%. According to this information, it can be concluded that about 75% of the population is 59 years of age or younger.
This can be verified by adding the percentages of each population 23.5% (19 years or less) plus 25.1% (twenty to thirty-nine years) plus 27.5% (forty to fifty-nine years) add up to 76.1 %.
So the correct answer is D. 59 years and younger.
