01 Which of the following formulas is incorrect?
Answer and explanation
Correct answer: D. MP = FC − NIT
Explanation: The basic identity is MP = FC + NIT, where NIT means indirect taxes minus subsidies. Rearranging it gives FC = MP − NIT, and the definition of NIT confirms option C. Therefore MP = FC − NIT is incorrect because it subtracts net indirect taxes instead of adding them; option D is the required answer.
