When the punter asks for '$10 each way' this is actually two bets, at ten dollars stakes each, totalling $20.
If the selection wins, the return is:
total stake + (stake x win odds) + (stake x place odds (usually 1/4 or 1/5 of win odds))
If the selection is placed but does not win, the return is:
place stake + (stake x place odds)
