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?

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)
