Which of the following is the MAXIMUM number of 10Mb audio files that a user can store on a CD- RW?
The correct answer is B. 70. A standard CD-RW holds approximately 700MB of data. Dividing 700MB by 10MB per file yields a maximum of 70 files.

Why each option
A standard CD-RW holds approximately 700MB of data. Dividing 700MB by 10MB per file yields a maximum of 70 files.
50 files would only use 500MB, leaving 200MB unused and not representing the maximum capacity.
A CD-RW disc has a standard capacity of approximately 700MB. Dividing 700MB by 10MB per audio file gives exactly 70 files, which is the maximum number that can be stored without exceeding the disc's capacity.
100 files would require 1000MB (1GB), which exceeds the 700MB capacity of a standard CD-RW.
120 files would require 1200MB, far exceeding the 700MB limit of a CD-RW disc.
