Answer & Step-by-step explanation:
This question is just a matter of reading the graph correctly. The question is basically asking us how much each color (or the education level) is taking up in the whole bar. So, you just subtract where the color ends from where the color starts.
1997 age 65 or older
Bachelor's degree or higher: 100 - 75 = 25%
College/associate's degree: 75 - 54 = 21%
High school graduates: 54 - 21 = 33%
Less than a high school diploma: 21 - 0 = 21%
Total: 25+21+33+21 = 100%
2007 age 65 or older
Bachelor's degree or higher: 100 - 69 = 31%
College/associate's degree: 69 - 46 = 23%
High school graduates: 46 - 13 = 33%
Less than a high school diploma: 13 - 0 = 13%
Total: 31+23+33+13 = 100%
Hope this helps :)
