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

.
