Help modifying query to honor min and max markups

I need modify this query to honor the minmk and maxmk, if mt = 'P' and either minmk and maxmk exist.
Not sure how to do that...

Currently, the query returns 125.00 for the first record and 2893.75. It needs to return 140.00 and 2815.00

Note: There are only 'P' (percentage) and 'F' (flat) markup types.

SELECT
    -- when the markup is a 'P' (percentage) multiply     
	CASE WHEN (SELECT c0.mt 
               FROM p.markups c0 
               WHERE c0.id = 'M07' AND 
                     c0.pid = 'M34' AND 
                     c0.pt = '107') = 'P' THEN
		TO_CHAR(u.price + (u.price * (SELECT c1.mk 
		                                FROM p.markups c1 
		                                WHERE c1.id = 'M07' AND 
		                                      c1.pid = 'M34' AND 
		                                      c1.pt = '107')) , 'FM999999999.00')
	ELSE
	-- when the markup is a 'F" (flat), so add it
		TO_CHAR(u.price + (SELECT c2.mk 
		                    FROM p.markups c2 
		                    WHERE c2.id = 'M07' AND 
		                          c2.pid = 'M34' AND 
		                          c2.pt = '107') , 'FM999999999.00')
		                          
	END as mkprice	
FROM u.unet u
WHERE u.id = 'M34' AND 
      u.pt = '107'

If I have this data in `p.markups`:
"id" , "pid", "pt" , "mt", "mk", "minmk", "maxmk", "exc"
"M07", "M34", "107", "P" , 0.25, 40     , 500    , 0

and this data in u.unet:
"id",  "pt" , "price"
"M34", "107",  100.00
"M34", "107", 2315.00
