A university is trying to determine what price to charge for tickets to football games. At a price of $21 per ticket, attendance averages 40,000 people per game. Every decrease of $3 adds 10,000 people to the average
number. Every person at the game spends an average of $3.00 on concessions. What price per ticket should be
charged in order to maximize revenue? How many people will attend at that price?

sorry, i don't know i just need points, i'm new here. chao

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.
