The metropolitan transit authority (mta) has just opened a new subway line (the orange line) in its underground transportation network. The orange line had a capital investment of $20 million, expected operating and maintenance expenses are $3 million per year, and the final salvage value at the end of a 40 year life is negligible. if the revenue generated by each customer is $3, how many customers per day will be required before the orange line can break even? The mta's hurdle (interest) rate is 5% compounded annually. assume there are 365 days in a year.
