A monopolist produces output with constant marginal cost equal to 1. There are two consumers who are potentially in the market for the good. Consumer A has inverse demand function pA(x)=5-x

and consumer B has inverse demand function

pB(x)=5K (5-x)

where K is a constant and 1

-Whatt are the Pareto efficient levels of consumption of the good by consumers A and B? Call these xA and xB respectively
