I have a problem in economics on Law of Equal Marginal Advantage. Please help me in the following question. The very last cents spent on each and every good should give up equivalent subjective profits according to the principle of: (i) Subjective preferences. (ii) Satiation. (iii) Demand and supply. (iv) Equal marginal utilities per dollar. (v) Diminishing returns.
What is the precise option from the above.
