A university dormitory has a total of 500 students. Each student's room is equipped with a smoke alarm. The smoke alarms have a minimum coverage area of 1,000 square feet. How many smoke alarms are required?
- 500
- B1,000
- C2,000
- D5,000
Exam tip
Count the number of rooms or students to determine the number of smoke alarms required, not the coverage area.
Why A is correct
Since each student's room requires one smoke alarm and each alarm has a minimum coverage area of 1,000 square feet, the total number of smoke alarms required is equal to the number of students, which is 500. The other options are incorrect as they do not reflect the actual number of students or the coverage area of each alarm.
