There's a monthly raffle at work for 5 parking spaces out back. There are about 30 people in my office. There's no limit to the amount of tickets you can buy. You can only win once. Otherwise, parking costs about $4 a day, or about $80 a month. Raffle proceeds go to charity. What's the optimal amount to spend on this? [more inside]

But none of us can really figure out what formula to use. [more inside]
