' ........... 8a) The demand price for a monopolistic rm's product is a function of quantity q and quality 5 : P(s, 6]) = s(a - bq), while the rm's production cost is a function of quality 5 only: C(s, q) = 0.552. Find all three stationary (i.e., critical) points of the monopolist's prot maximization problem. Enter each of them separately in the boxes below. For any given critical point, enter the solution for s as the rst one. Do not use spaces. For example, if one of the points you found is q = b2/(7a) and s = 19/61, enter this point as follows: s=b/a,q=b"2/(7a)
