On a certain route, an airline carries 5000 passengers per month, each paying $70. A market survey indicates that for each $1 in
Mkey [24]

Answer:

$85

Step-by-step explanation:

5000 x $70 = $350,000

4950 x $71 = $351,450

4900 x $72 = $352,800

etc.

Create an equation for the monthly revenue:

f(n) = (5000 - 50n) x (70 + n)

     = 350000 + 5000n - 3500n - 50n²

     = 350000 + 1500n - 50n²

where n is the amount the ticket price is increased from $70.

Differentiate, equal to zero and solve for n to find the value of n when the monthly revenue is at its maximum:

f'(n) = 1500 - 100n

1500 - 100n = 0

1500 = 100n

15 = n

Therefore, the maximum monthly revenue is when n = 15.

So the cost of the ticket will be 70 + n = 70 + 15 = 85

G(n) = n2 − 20n + 95 Rewrite the function in vertex form by completing the square. Show your work.
Aleksandr [31]
Y = n^2 - 20n + 95
y - 95 = n^2 - 20n
y - 95 + 100 = n^2 - 20n + 100
y + 5 = (n - 10)^2
y = (n - 10)^2 - 5


answer is : G(n) = (n-10)^2 - 5
