            Dear visitor,

            Let me note that your formulation of the question in the post is INCORRECT and NONSENSICAL.

            The correct formulation is THIS : 

              Write the tuition cost as a function of time.

            Learn it to use correctly in the future.



Solution 

ANSWER.  T(t) = 1827 + %28%282907-1827%29%2F%281995-1989%29%29%2A%28t-1989%29,

         where t is time in years after 1989.



It is the same as  T(t) = 1827 + 180*(t-1989).


It is a standard interpolation/extrapolation linear function.
