Answer:
70% (Sorry, had to use the word "com" instead...)
Explanation:
The question is asking what percent of students who graduated one of these three schools, graduated from either com laude or magna com laude. You need a total of how many students graduated com laude and how many from magna com laude. 4 graduated from magna com laude, and 10 graduated from com laude. That's 14. Now we need a total of how many students graduated in total. 14 graduated from com laude or magna com laude, and 6 graduated from summa com laude for a total of 20 who graduated. So you just need to do 14 divided by 20, and you'll get the decimal from which you can get a percent. 14 divided by 20 is 0.7. So, that's 70%. 70% of students who graduated, graduated from Magna com laude or Com laude.
