The Atlanta Braves marketing staff knows it has 20,000 seats in the stadium priced at $20 per ticket, 13,000 priced at $30 per ticket, and 17,000 priced at $50 per ticket. Jim says that the marketing materials should say that average ticket price is $30, Jill says it should be $33, and Fred says it should be $35.20. Who is most correct?

Respuesta :

Answer:

Jill is most correct and it should be $33

Step-by-step explanation:

Total number of seats = x =20000+13000+17000

x =50000

Total cost of seats as per the price;

a = 20*20000

a =400,000

b = 30*13000

b =390,000

c = 50*17000

c =850,000

Average  = (a + b + c) /x

Average = (400,000+390,000+850,000)/50,000

Average cost = 1,640,000/50,000

Average cost = $32.8
