A university dormitory has 500 single-occupancy rooms. A specified maintenance task calls for replacing exactly one existing smoke alarm in each of those single-occupancy rooms. How many replacement alarms are needed for this task?
- 500
- B1,000
- C2,000

Where to look it up
Explicit exercise assumptions; not a universal code requirement.
Why A is correct
The specified task requires 500 × 1 = 500 replacement alarms. This counts only the described replacements; it does not establish how many alarms the building must have or verify the existing alarm design. No floor area or coverage assumption is needed.
