Question 460479
The number of files N of the same size that a computer's hard disk will hold
 varies inversely as the size of S of the files. 
Greg's hard disk will hold 1300 files if each is 12,000 bytes long.
:
Find the total capacity of the hard drive:
1300 * 12000 = 15,600,000 bytes
:
 How many files of each is 120,000 bytes long.
{{{15600000/120000}}} = 130 files
:
 How many files will the disk hold if each is 40,000 long?
{{{15600000/40000}}} = 390 files
