A computer store sold a total of 300 items in a month, and sold six times as many hard drives as they did CDROM drives, and half as many floppy drives as hard drives, how many of each item were sold?

Let H = number hard drives
C = number CDRoms
F = number floppy drives.
===========================
H = 6C
(1/2)H = F
F + H + C = 300
======================
Three equations.
Solve for H, C, F.
