you are leaving your house to get to your destination on the other side of town, but there is only one way of getting there: a bridge that crosses a river. when you get to the bridge, there is a serial killer there and will kill you if you try to cross the bridge. you go down to the river where you find a ferryman who will take you across the river for $15. you only have $7.50 and you cannot swim. there is no hope of getting past the serial killer, not even with a gun.
You go further down the river to find another ferryman who can take you on a river tour of the city, but he doesn't make port on the side of the river you need to go to. he says it will cost $7 to take the tour, but it will cost another $5 to go out of his way to bank on the side of the river you need to go to; remember, you only have $7.50.
You come back up the river near the bridge to find a man who rents kayaks out for $5 for every 10 minutes. however, it would take at least 20 minutes to row across the river, costing $10. (not to mention you'd have to row back to return the kayak to him). So, how do you get to your house?
