Homework Help: Math

Posted by Jackie on Thursday, February 9, 2012 at 7:39pm.

The hourly operating cost of an airplane, which seats up to 405 passengers, is estimated to be $5,500. If an airline charges each passenger a fare of $100 per hour of flight, find the hourly profit P it earns operating the airplane as a function of the number of passengers x. (Be sure to specify the domain.)

What is the least number of passengers it must carry in order to make a profit? HINT [The cost function is constant (Variable cost = 0).]

Profit: P(x)=100x-5500

I solved it:
P(x)=0
100x-5500=0
5500/100=55 Passengers.

It is wrong, I don't understand.
Thank You
