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 20, how many more dollars, in terms of x, will it cost per person? Choose the most appropriate option.
A) x/6 B) x/16 C) x/20 D) 3x/40 E) 3x/80
Just plugging in values   X= 200   Cost per person if we consider 10 = 20   Cost per person if we consider 20 = 10   Difference between costs is 10 dollars.   Plugging in the value of x into the answer choices, let's see which one yields a result of 10. And that is x/20.
