Final Answer : A, Explanation :  Lenny's profit-maximizing level of output is where marginal cost equals marginal revenue. The marginal cost is constant at $2, so the marginal revenue must also be $2. The demand curve shows that the marginal revenue is $2 at a quantity of 4 cups. Therefore, Lenny's profit-maximizing level of output is 4 cups. The price per cup is then determined by the demand curve, which shows that the price is $6 at a quantity of 4 cups.
