Answer: 40%
Step-by-step explanation: Assuming there are only three categories (students wearing either bandanas, glasses, or hats), you would need to add the given percentages, and subtract them from 100 because that is the whole percentage of the students.
10% (bandanas) + 50% (glasses) = 60% (bandanas and glasses)
100% (bandanas, glasses, and hats) - 60% (bandanas and glasses) = 40% (hats)
40% of the students are wearing hats.
