A) $200 B) $300 C) $400 D) $500 E) $600 A) $200 B) $300 C) $400 D) $500 E) $600

A) is the difference between total cost and total fixed cost. B) increases as the marginal product of labor increases. C) decreases as the average product of labor increases. D) is the change in total cost arising from a one-unit increase in output. E) equals the change in variable cost divided by the change in fixed cost when output increases by one unit.
