I went like this:

Melbourne +9
Sydney -10
$50 returns $152

Port Power -8
Melbourne +9
Sydney -10
$40 returns $171.60

Brisbane -15
Melbourne +9
Sydney -10
$40 returns $184.50

Brisbane -15
Port Power -8
Melbourne +9
Sydney -10
$30 returns $195

Bank was at $651.50 which now drops to $491.50

I still think it's much more fun betting with winnings than it is with the bread and milk money!
