To achieve profit maximization, a firm should adjust its resource allocation until the _______ of labor divided by the wage is equal to the _______ of capital divided by the price of capital.

The firm wants each dollar spent on labor to add the same amount of output as each dollar spent on capital. Other options are incorrect because Total product is the overall amount of goods produced, not the change from adding a new unit; Average product looks at output per input unit, but it ignores how much extra output a new unit gives.
