A baseball team plays in a stadium that holds 48000 spectators. With the ticket price at $12 the average attendance has been 21000. When the price dropped to $11, the average attendance rose to 24000. Assume that attendance is linearly related to ticket price. What ticket price would maximize revenue? $

Expert Solution
Step 1

Let the ticket price be $x and attendance is linear function of x, say Px

When the ticket price at $12, average attendance is 21,000. Therefore, P12=21,000

When the ticket price is $11, average attendance is 24,000. Therefore, P11=24,000

Therefore, the slope of the line joining 11,24000 and 12,21000 is

m=21,000-24,00012-11=-3000

Therefore, the equation of line joining these two points is

Px=-3000x+57000           (i)

Eq.(i) represents the price function
