Revenue from Monorail Service, Mars The Utarek monorail, which links the three urbynes (or districts) of Utarek, Mars, charged 5 per ride and sold about 14 million rides per day. When the Utarek City Council lowered the fare to 3 per ride, the number of rides increased to 18 million per day.

a. Use the given information to find a linear demand equation.

b. Find the price the City Council should have charged to maximize revenue from ridership. What is the corresponding daily revenue?

c. The City Council would have needed to raise 48 billion in revenues from ridership each Martian year (670 days9) to finance the new Mars organism research lab. Would this have been possible by charging a suitable price?
