Can you tell me why you don't think this is the case??

(not 260, for the market value is already depreciated
when the second producer puts his products on the market
in asmuch as the prevailing market value of c is 80 then)
the total profit rate for B is 80/160 (not 80/100)
(higher than the profit rate of A notlower than prate for A
since for A, the prate is
> 80/180) .
NEXT period prate will of course be equalised since B and A
both would buy the c at 80. To me, therefore, 80/160 is the
**only** economically relevant profit rate.
