Suppose the consumers have preferences with the following MRS of F in terms of C MUF 9CJ MRSFC = MUC FJ and MUK CK MRSK FC MUK FK where J, K are labels for the consumer, not powers. Suppose the economy has 25 units of good F and 32 units of good C . If consumer J is endowed with 11 units of good F and the consumers are given a Pareto efficient allocation, how many units of good C will consumer **K** be provided
