The percent of individual trivia test scores at or above 80 points is approximately 27%, which is closest to option B: 33%.
To find the percent of individual trivia test scores that are at or above 80 points, we need to count the number of scores that are 80 or higher, and divide that by the total number of scores.
In this case, there are 4 scores of 80 or above out of a total of 15 scores (5 students in each team x 3 teams), so the percent is (4/15) x 100 = 26.67%.
Rounding to the nearest whole number, the closest percent is 27%, which is closest to option B: 33%.
