URGENT! How do you calculate for marginal cost against fixed cost. E.g., a company produces 2 pairs of shoes at $390.00. If it produces 1 more pair (making total production 3), total cost is $600.00. If no production is made, the fixed cost is $130. With this scenario, how do you compute for the marginal cost if it produces no shoes at the fixed rate indicated.
