2-Jule decided to buy a minor league base team from Paul. Each time she rents the stadium, she is charged $8000. From pas experience, she can expect that on a rainy night only 2000 will attend the game, on a clear night 2500 will attend, on a hot muggy night 3000 will attend, and on a warm clear night 4500 will attend.

The weather service predicts that rainy nights occur 22% of the time, clear nights 32% of the time, hot muggy nights 21% of the time, and warm clear nights occur 25% of the time.
a) If she charges $4 per person, what can she expect to earn each game?
b) What is the breakeven ticket price that should be charged?
