Why the man is forced to get off the subway just 5 stops away from where he began ?

Question

A man in New York City has $10. He spends $6.50 on tulips, and $3 on burger and coke. He then gets on the subway which will take him 7 stops for 50 cents. But he is forced to get off of the subway just 5 stops away from where he began.

Why is this?

Answer 1

That is the last stop

Answer 2

The smallest cost of one ticket one can buy is 50 cents for a max of seven stops. His stop is only 5 stops from where he boarded.
