12) An oligopoly producing a homogeneous product is composed of three firms that act
like a cartel. Assume that these three firms have identical cost schedules. Assume also
that if any one of these firms sets a price for the product, the other two firms charge the
same price. As long as they all charge the same price they will share the market equally;
and the quantity demanded of each will be the same.
Below are the total-cost schedule of one of these firms and the demand schedule that
confronts it when the other firms charge the same price as this firm. Complete the
marginal-cost and marginal-revenue schedules facing the firm.
(a)What price would be charged, what output would be produced, and what profit
would be made by this firm?
(b)If the firms collude to maximize joint profits, what would be the industry price,
output, and profit?
