Question

Suppose that 30% of all students who have to buy a text for a particular course want a new copy. If there are 150 students in the course, how many students are likely to prefer a new copy of the textbook?

A) 45 students
B) 75 students
C) 90 students
D) 120 students

Answer 1

To determine the number of students preferring a new textbook, multiply the percentage (30%) by the total number of students (150), which equals 45 students.

Step-by-step explanation:

To calculate the number of students likely to prefer a new copy of the textbook, we would use the given percentage and multiply it by the total number of students in the course.

The formula to use is: Number of Students Preferring New Textbook = (Percentage preferring new textbook) x (Total number of students)

Given that 30% of students prefer new textbooks and there are 150 students in the course, we calculate:

0.30 x 150 = 45

Therefore, 45 students are likely to prefer a new copy of the textbook. The correct answer is A) 45 students.
