A mоnоpоlisticаlly competitive firm fаces the following demаnd curve for its product: Price Qty $20 0 $18 1 $16 2 $14 3 $12 4 $10 5 $8 6 $6 7 $4 8 $2 9 Suppose that the marginal cost of the first unit is $4, the marginal cost of the second unit is $2, the marginal cost of the third unit is $4, the marginal cost of the fourth unit is $6, the marginal cost of the fifth unit is $8, the marginal cost of the sixth unit is $10, the marginal cost of the seventh unit is $14, and the marginal cost of the eighth unit is $18.What is the firm's profit-maximizing level of output? Hint: You will need to write this table down and then add a few columns in order to answer the question.
