A firm produces a certain good and has two plants. To produce y1y_1y1​ units of the good in plant 1, the total cost for the firm is c1(y1)=y1×y1c_1(y_1) = y_1 \times y_1c1​(y1​)=y1​×y1​. To produce y2y_2y2​ units of the good in plant 2, the total cost for the firm is c2(y2)=y2×y2c_2(y_2) = y_2 \times y_2c2​(y2​)=y2​×y2​.

A firm produces a certain good and has two plants. To produce y₁ units of the good in plant 1, the total cost for the firm is c₁(y₁) = y₁ × y₁. To produce y₂ units of the good in plant 2, the total cost for the firm is c₂(y₂) = y₂ × y₂. Each unit of good produced by the firm is sold at price equal to 3. The profit level of the profit-maximizing firm is (A) 9 (B) 0 (C) The profit maximization problem does not have a solution (D) None of the above

Also written as: A firm produces a certain good and has two plants. To produce y_1 units of the good in plant 1, the total cost for the firm is c_1(y_1) = y_1 * y_1. To produce y_2 units of the good in plant 2, the total cost for the firm is c_2(y_2) = y_2 * y_2. Each unit of good produced by the firm is sold at price equal to 3. The profit level of the profit-maximizing firm is
