On a certain route, an airline carries 9000 passengers per month, each paying $200. A market survey indicates?

that for each $1 decrease in the ticket price, the airline will gain 50 passengers.





1. Express the number of passengers per month, N, as a function of the ticket price, x.





2. Express the monthly revenue for the route, R, as a function of the ticket price, x.





1. N(x)=





2. R(x)=

On a certain route, an airline carries 9000 passengers per month, each paying $200. A market survey indicates?
1. N(x) = 9000 +50(200-x) = 19,000 - 50x





2. R(x) = 19,000x - 50 x^2
