Answer 1

I like @kaf 's answer, just want add that you may reduce the number of case by this

select case when results BETWEEN 0 AND 3 then results * 4
            when results BETWEEN 4 AND 7 then results * 8
            when results BETWEEN 8 AND 9 then results * 13
            when results >= 10 then 150
            else -1 
        end as CaseResults
from (select [dbo].[YearsInService]([DateEngaged],getdate()) results
      from yourTable
     ) Temp
