A baseball team plays in a stadium that holds 68000 spectators. With the ticket price at $8 the average attendence has been 29000. When the price dropped to $5, the average attendence rose to 34000. Assume that attendence is linearly related to ticket price.

Answer 1

You know, I don't mind helping with answers, but don't make me come up with the questions, too!. I assume you want the maximum revenue.

Let x = the number $3-price drops.Then the revenue is
r = (8-3x)(29000+5000x)
Now just find the maximum of r(x), keeping in mind that the stadium only has 68000 seats.

Maybe you are just looking to find the price needed to fill the stadium. But no calculus at all for that.

Your choice!
