Question

Thirty percent of the class scored at least 80 points. If there are 50 students in the class, how many scored at least 80 points?

A) 15 students
B) 20 students
C) 10 students
D) 30 students

Answer 1

To determine the number of students who scored at least 80 points, calculate 30% of 50. Multiplying 0.30 by 50 gives 15, indicating that 15 students scored at least 80 points.

Step-by-step explanation:

To find out how many students scored at least 80 points, we need to calculate 30% of the class size. Since there are 50 students in the class, we will use the following equation:

Number of students scored ≥ 80 points = 30% of 50

Number of students scored ≥ 80 points = 0.30 × 50

Number of students scored ≥ 80 points = 15

Therefore, the correct answer is A) 15 students.
