A university is trying to determine what price to charge for tickets to football games. at a price of $20 per ticket, attendance averages 40,000 people per game. every decrease of $5 adds 10,000 people to the average number. Every person at the game spends an average of $5.00 on concessions. what price per ticket should be charged in order to maximize revenue? How many people will attend at that price?

The weekly amount spent by a company for travel has an approximately normal distribution with mean = $550 and standard deviation = $40. a) what is the probability that the actual weekly expense will exceed $570 for more than 20 weeks during the next year? (note: one year = 52 weeks) b) what is the probability that actual weekly expenses exceed $580 for 10 or more, but 16 or fewer weeks during the next year?
