At ge medium price. It's pretty obvious to be honest but i guess i'll calculate it for you.
29,563 lobsters to 90 cooking. This should cost you 1.803.343gp buying med selling med(raw-cooked)
17,322 monkfish to 94. This should cost 1.247.184
24,238 sharks to 99. This is 1.599.708
That's 4.650.235gp.
It's not that hard to calculate it yourself,you know? Just look at the ge prices,subtract cooked price from raw then you are left with the gp loss per fish,x that with the amount of fish you have to cook and there you go.
