4 Nimbus Lid makes brooms and then sells them door-to-door. Here is the relationship between the number of workers and Nimbus's output during a given day. Workers Output Marginal Total cost Average Marginal product total cost cost 0 20 50 90 YOU AWN -O 120 140 150 155 a Fill in the column of marginal products. What pattern do you see? How might you explain it? b A worker costs $100 a day and the firm has fixed costs of $200. Use this information to fill in the column for total cost. c Fill in the column for average total cost. (Recall that ATC = TC/Q.) What pattern do you see? d Now fill in the column for marginal cost. (Recall that MC = ATC/AQ.) What pattern do you see? e Compare the column for marginal product with the column for marginal cost. Explain the relationship. f Compare the column for average total cost with the column for marginal cost. Explain the relationship
