Here is my problem. I want to know how many boards I can get out of a piece of wood.

I have a length that is 192 inches.

What I need to do is cut single boards that start with board 1 at 8 inches wide and each board after descreases by .5 inch.
so I would have

board 1 8" wide
board 2 7.5" wide
board 3 7" wide

and so on. But I would like to know how many I can get. This way I can change the .5 inch width to something else.

Thanks
