Add up the number of White candidates .. W
Add up the TOTAL number of candidates .. White + Minority .. T
Then it's W/T * 100

195+38+16+17+19+48+9+4+3+5 = 354
195+38+16+17+19 = 285
% white = 285/354 * 100 = 80.5

Just add up all the numbers = total number of graduates.
Add up the numbers under whites = white graduates.
Total number of whites divided by the total number of students equals the percentage of the graduating class who are whites.
