its really a pricing problems

Question 3 - Pricing for Different Customer Segments (10 points) Septa is the manager of a bus company that serves the Philadelphia-Washington DC route. The demand curve facing each bus is: Number of Seats Sold = 80 - 0.5 x Price The variable cost of serving each seated customer is $20. (For questions where Septa charges multiple prices, assume that there are segmentation fences in place such that the customers with higher WTP will pay the higher price.) What is the maximum WTP in the market? (1 points) If Septa charges a price of $80 per seat, what is the profit for each bus? (1 point) If the price is $80 per seat, how much is the Money Left on the Table"? (1 points) If Septa charges 2 prices, $120 (High Price) and $60 (Low Price), what is the profit for each bus?
