A computer store sold a total of 300 items last month.
The store sold 6 times as many hard drives as they did CD_ROM drives,
# of ROM drives: x
# of hard drives: 6x
-----
and half as many floppy drives as hard drives.
# of floppy drives = 3x
---
Based on this information, how many of each item were sold?
x + 6x + 3x = 300
10x = 300
x = 30 # of RoM sold
6x = 180 # of hard sold
3x = 90 # of floppy sold
