GetThere Airlines currently charges  200 dollars per ticket and sells 40,000 tickets a week. For every  10 dollars they increase the ticket price, they sell  800 fewer tickets a week. How many dollars should they charge to maximize their total revenue?

Ans: ticket price should be= \$ 350

soln:

current revenue=\$ 200*40,000=\$ 8,000,000

now, let they suppose  increase the price by=\$ 10*x, x is a natural number

no ticket loss per week will be= 800*x

now, revenue =f(revenue)=(200+10*x)*(40,000-800*x)= -8,000*x2+240,000*x+8,000,000

for maximum or minimum--differentiating f(revenue)=0

=>-16000*x+240,000 = 0

=>x=15

by double differentiating f(revenue) we get <0

=>at x=15 it will be maximum value.

Ans:ticket should be= \$200 + \$ 10*15 =\$ 350.

Christ! Anyone that can decipher your bullshit infused slop could more easily figure out how to solve the problem without it.
