A hockey team plays in an arena with a seating capacity of 15,000 spectators. With the ticket price set at , average attendance

Goshia [24]

Answer:

Ticket price 11,5 $

R(max) = 132750 $

Step-by-step explanation:INCOMPLETE QUESTION

The ticket price is missing

We will assume 12 $

Let call x the decreasing number of the ticket price

The revenue is

R = ticket price * numbers of spectator

R(x) = ( 12 - x ) * ( 11000 + 1000*x ) for all 0 ≤ x ≤ 4 ( the seating capacity is 15000 )

R(x) = 132000 + 12000*x - 11000*x - 1000*x²

R(x) = 132000 + 1000*x - 1000*x²

Taking derivatives on both sides of the equatio we get:

R´(x) = 1000 - 2000x

R´(x) = 0 ⇒ 1000 - 2000x = 0

x = 1000/2000 ⇒ x = 0,5 $

We notice that R´´(x) < 0 then we have a maximum for x = 0,5

and the price is 12 - 0,5 = 11,5 $ for ticket

and the R(max) is

R(max) = 132000 + 1000*0,5 + 1000* (0,5)²

R(max) = 132000 + 500 + 250

R(max) = 132750 $

Answer:

(-18,9)

Step-by-step explanation (work shown in picture attached):

1) The first step in solving by substitution is to isolate the y-term in one of the equations if it is not already isolated. Isolate y in the first equation by dividing both sides by -2. This leaves us with the equation $y = \frac{-x}{2}$

2) Now, substitute $\frac{-x}{2}$ for the y in the second equation. Simplify and isolate x. (You can multiply everything by -2 to get rid of the fraction.) This leaves us with x = -18.

3) We've found the x-value of the solution, -18. Now, substitute -18 for x back into one of the original equations (I chose the first one because it was simple) and isolate y. This gives us y = 9. Thus, in point form, the answer is (-18,9).
