A baseball teams attendance depends on the number of games it wins per season and on the price of its tickets.The demand function it faces is Q = N(20 - p),where Q is the number of tickets (in hundred thousands)sold per year,p is the price per ticket,and N is the fraction of its games that the team wins.The team can increase the number of games it wins by hiring better players.If the team spends C million dollars on players,it will win .7 - 1/C of its games.Over the relevant range,the marginal cost of selling an extra ticket is zero. a.Write an expression for the firms profits as a function of ticket price and expenditure on players. b.Find the ticket price that maximizes revenue. c.Find the profit-maximizing expenditure on players and the profit-maximizing fraction of games to win.
