Question

The following function represents the profit P(n), in dollars, that a concert promoter makes by selling tickets for n dollars each:

P(n) = -250n2 + 2,500n - 5,250

Part A: What are the zeroes of the above function, and what do they represent? Show your work. (4 points)

Part B: Find the maximum profit by completing the square of the function P(n). Show the steps of your work. (4 points)

Part C: What is the axis of symmetry of the function P(n)? (2 points

Answer 4

A) P(n) means the profit of selling tickets at n price. So, say P(12) = 10,000. This means the profit is $10,000 if the they decide to sell the concert tickets at $12 each.

find zeros means find what value of n gives P(n) = 0. suppose n is, like P(500) = 0, this means there would be no profit if each ticket cost like $500 each. Of course you to find the actual value of n that makes the equations equal 0.

Answer 5

B and C are just calculator problems.
ill leave that to @ganeshie8

Answer 6

Wait so I'm not understanding what the zeros mean?

Answer 11

I think i got b and c. I just need a

Answer 12

for b i gotP(n)=-250n^2 +2,500n-4,000
p(n)'= -500n + 2500
pur p(n)'=0
u will get n = 5.
-250(5^2) + 2500(5) - 4000
= 2250

Answer 13

for c i got(b/2*a)
b=2500 and a=-250
-(b/2*a)=(2500/500)
=5
