Springfield Express is a luxury passenger carrier in Texas. All seats are first class, and the following data are available:
Number of seats per passenger train car 90
Average load factor (percentage of seats filled) 70%
Average full passenger fare $ 160
Average variable cost per passenger $ 70
Fixed operating cost per month $3,150,000

A. What is the break-even point in passengers and revenues per month?

I understand this may be a homework question, but if you can at least help direct as to how to set it up, that would help me out. As I am looking in my book, and not exactly understanding it.
Thanks

Yes it can be done on abacus and amadeus... who wants to know that ?
