Suppose that Timmy lives in a neighborhood where graffiti is common. People’s cars and the sides of houses are often vandalized with graffiti. In response to the vandalism, the people in the neighborhood have proposed a voluntary community fund to pay for extra police patrols. There are 1000 people in Timmy's neighborhood, and each is recommended to contribute $10 a month. Timmy’s car has recently been vandalized and he is concerned it may happen again. Although he believes that he will benefit from the extra police patrols, Timmy has decided to take a free‑rider approach. Given his thinking, how much will Timmy contribute to the fund?
