First let's find the value of f%28273%29


f%28x%29+=+67x-125


f%28273%29+=+67%28273%29-125 Replace every 'x' with 273


f%28273%29+=+18291-125


f%28273%29+=+18166


----------------------------------


Now let's find the value of f%28195%29


f%28x%29+=+67x-125


f%28195%29+=+67%28195%29-125 Replace every 'x' with 195


f%28195%29+=+13065-125


f%28195%29+=+12940


----------------------------------


We have the information we need. We can now compute what the book/teacher is asking.


%28f%28273%29+-+f%28195%29%29%2F%28273-195%29+=+%2818166-12940%29%2F%28273-195%29


%28f%28273%29+-+f%28195%29%29%2F%28273-195%29+=+5226%2F78


%28f%28273%29+-+f%28195%29%29%2F%28273-195%29+=+67


----------------------------------


The final answer is 67
