A baseball team plays in a stadium that holds 51,000 spectators. With ticket prices at $10, the average attendance had been 49,000. When ticket prices were lowered to $8, the average attendance rose to 51,000
a. Find the demand function (price p as a function of attendance x), assuming it to be linear

asked by Anon
  1. You have two points on the graph:
    (10,49) and (8,51)

    price went down 2
    attendance went up 2

    So, the slope is -1, making the demand function

    p-49 = -1(x-10)
    or
    p(x) = 59-x

    where x is measured in thousands
