Understand the definition of the marginal product (MP) of a factor: it measures the additional output produced by using one more unit of that input, holding other inputs constant.
Recall that marginal product relates to output, not directly to revenue or costs. It tells us how total output changes when the input quantity changes by one unit.
Marginal revenue refers to the additional revenue from selling one more unit of output, which is different from marginal product since it involves price and output sold.
Total cost and average cost relate to expenses of production, not the physical quantity of output produced by an additional input unit.
Therefore, the marginal product of a factor specifically shows the change in total output resulting from an additional unit of that factor.
