Suppose there are many sellers with used cars that they value at amounts ranging from​ $0 to ​$13,000. The distribution is even​ (or "uniform"​); ​thus, if you randomly selected all cars worth under​ $6,000, the expected value​ (for the​ seller) would be​ $3,000 (the midpoint from​ $0 to​ $6,000). There are many​ buyers, and they value each car ​$900 higher than sellers. For​ example, a car worth​ $2,000 to a seller would be worth ​$2,900 to a buyer. Find an equilibrium price such that it makes sense for buyers to​ buy, given what they know about sellers. Under these​ conditions, the equilibrium price of a used car will be ​$. ​(Enter your answer as a whole number​.)
