Proper Place For Sub Select?

I have a very simple query that gets a field to use as constraints in another query.

Code:

SELECT A.RIN
FROM apcType T
INNER JOIN apcAttribute a on A.T = T.RIN
WHERE T.Name like '%Sales'

The results of the first query are used in the following query where it is bolded and marked with and <<<<========

Code:
SELECT AP.Arg2, AP.Arg3, M.Parcel,
M.Serial, M.Name, M.Acres, M.District,
V.YearBuilt, V.Code, V.Size,
(SELECT SUM(V1.Acres)
FROM TRValue V1
WHERE V1.Year = V.Year and V1.Parcel = V.Parcel and
SUBSTRING(V1.Code, 1, 1) = 'L'

[code]....

My question is How can I fold the first query into the second?
