Homework Answers
In a perfectly competitive market to maximize profit, firms set marginal revenue equal to marginal cost (MR=MC). MR is the slope of the revenue curve, which is also equal to the demand curve (D) and price (P).
Here the price is $7, so when the horizontal line is drawn then this curve is said to be the MR curve and demand curve. Therefore, MR=MC gives the maximum profit output is 10 units. Option C is correct.
