I'm not sure I understand the question, Commander_Fallout, but let me price it out for you:
Darkwood Composite Longbow (masterwork) = 430gp
Adaptive Strength = +1000gp
Enchancement Costs =
+1 = +2000gp
+2 = +8000gp (+6000gp over +1)
+3 = +18000gp (+16000gp over +1)
+4 = +32000gp (+30000gp over +1)
Each of the effects are a +1 equivalent, so with +2 and both effects, the bow would cost out at +4
So, the cost of the bow is:
Darkwood Composite Longblow +1, Adaptive = 3430gp
Then just pay the costs for amount over the base +1 enchantment noted above (6000gp for +2, etc) and ratchet it up to whatever level you wish to buy. At full power, as stated, it would be:
Darkwood Composite Longbow +2, Ghost Touch, Fiery, Adaptive = 33430gp
