Answer 2

-- You Can Use ROUND Function to Round Up The Column you want. 
     select OrderID 
      , ItemID 
      , '$' + cast(price as varchar (7)) as [Price] 
      , ROUND((price) * 0.06,2) as [Sales Tax] 
      , ROUND((price) * 0.06 + (price),2) as [Subtotal] 

      from ORDER_ITEM 
      where price >= (20)
