You can put this solution on YOUR website!
The process you need to use is to say that the value,  , is equal to the age,  , times the rating,  , times a constant of proportionality,  .
then plug in the values for , , and and calculate the value for . Then you can calculate the value for any age and rating.
The only thing that is a little iffy is that you don't say when this problem was written. If this is a 2002 problem, the the age of a 2001 wine is one year. On the other hand, if this is a 2011 problem, a 2001 wine is 10 years old. Whatever it is, you get different values of .
