you have two points (x in thousands)
(9,30) and (6,37)
the slope is -7/3 so
p(x) = -7/3 (x-9) + 30
A baseball team plays in a stadium that holds 74000 spectators. With the ticket price at $9, the average attendance has been 30000. When the price dropped to $6, the average attendance rose to 37000.
Find the demand function p(x), where x is the number of spectators. (Assume p(x) is linear.)
