The cost to rent a small bus for a trip is x dollars, which is to be shared equally among the people taking the trip. If 10 people take the trip rather than 16, how many more dollars, in terms of x, will it cost per person?
~$x \over 6$~
~$x \over 10$~
~$x \over 16$~
~$3x \over 40$~
~$3x \over 80$~
是how many MORE dollars!
