Please always copy the list on your responses as others may be interested.
Something like this should work. I am not sure how inefficient it is.
select location_id, SUM((sold_parts_amount_dly + sold_labor_amount_dly)
- cost_amount_dly) /
SUM(sold_parts_amount_dly + sold_labor_amount_dly) from sales s1 where
(select SUM(sold_parts_amount_dly + sold_labor_amount_dly) from sales
s2 where s2.location_id = s1.location_id) > 0 group by location_id;
