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.

I don't understand what is wrong

Thank You

**Steve**, Friday, February 10, 2012 at 10:01amhourly revenue = 100p for p passengers

hourly cost = 5500

revenue=cost when

100p = 5500

p = 55

looks fine to me. why do you think it's wrong? anything over 55 passengers makes a profit, at $100/hr per extra passenger.
