the $1 coin dispenser ..
this machine has 10 manual settings to dispense fixed
numbers of $1 coins. If you could chose any combination
of these settings 'once per transaction' to evenly exchange
coins for paper currency .. what settings would dispense the
precise numbers of coins for any cash transaction up to $1,000?
Congratulations to these solvers as of
Hank City, Albert Frank, Joshua Green, LW Luk and Luc Vingerhoets.
