For the remaining three questions in this part, consider fish and chips as perfect complements. That is, a consumer obtains the consumption benefit of $20 for fish and $12 for chips only if he eats both fish and chips. For other consumption behaviors (eating only fish, only chips, or nothing), the consumption benefit is zero.

(f)(6%) Suppose that KFF has entered into the market, and McDaniel sells fish and chips separately. Let \( pA^K \) be KFF's price of fish, and \( pA^M \) McDaniel's price of fish and \( p_B^M \) McDaniel's price of chips. Find out prices and McDaniel's profit in Bertrand equilibrium.
