here's a quick and dirty worked solution i did for fun since some pals goaded me to do this... (just check tab p1 for all of the results - p2 and p3 are for the variants) -- one tiny macro just to simulate/recalc

if someone has a more elegant solution short of running it all via vba (which is really the legit way to do it), post it here, i'd be curious to see a better way of doing this via spreadsheet

i think i did it right (I pretty much got the right answers...)
