Of the students who are in Grade 12, what percentage prefer the Wolves mascot?

Answer & explanation

Correct answer: D. 55%

The question asks for the percentage of students in Grade 12 who prefer the Wolves mascot. First, identify the total number of students in Grade 12 from the table. The row for Grade 12 shows a total of 20 students. This will be the denominator. Next, find the number of students in Grade 12 who prefer the Wolves mascot. The table shows this value is 11. This will be the numerator. To find the percentage, calculate (11 / 20) * 100. This is equal to 0.55 * 100, which is 55%. A is incorrect because it is the percentage of all 50 students who are in Grade 12 and prefer the Wolves mascot (11/50 = 22%). B is incorrect because it is the percentage of all 50 students who prefer the Wolves mascot (22/50 = 44%). C is incorrect because it is the percentage of students who prefer the Wolves mascot that are in Grade 12 (11/22 = 50%), which reverses the condition in the question.
