ECONOMICS (CBSE/UGC NET)

Detailed explanation-1: -The law of supply says that a higher price will induce producers to supply a higher quantity to the market. Because businesses seek to increase revenue, when they expect to receive a higher price for something, they will produce more of it.

Detailed explanation-2: -To maximize profits, the firm should set marginal revenue equal to marginal cost. Given the fact that this firm is operating in a competitive market, the market price it faces is equal to marginal revenue. Thus, the firm should set the market price equal to marginal cost to maximize its profits: 9 = 3 + 2q, or q = 3.

Detailed explanation-3: -The Profit Maximization Rule states that if a firm chooses to maximize its profits, it must choose that level of output where Marginal Cost (MC) is equal to Marginal Revenue (MR) and the Marginal Cost curve is rising.

Detailed explanation-4: -Generally, the main goal of firms is to maximize profits. Profit maximization is achieved by a firm that produces an output in which its marginal cost and marginal revenue are equal (MC=MR). Therefore, the profit maximization is set by the output level produced by a firm which will generate the greatest profits.
