Suppose in Pakistan, all the firms are identical with identical cost curves which mean industry is perfectly competitive. Now please consider this following information about the industry: A representative firm’s total cost is given by the equation TC = 100 + q2 + q where q is the quantity of output produced by the firm. You also know that the market demand for this product is given by the equation P = 1000 – 2Q where Q is the market...

In C++ All guests in ABC Hotel are either Elite members (meaning they get a free breakfast) or Standard members (meaning they do not get a free breakfast). They collect points for every stay-Elite members earn 100 points for every day stayed in the hotel (so 2 days would be 200 points) and Standard member earns 50 points for every stay (so 3 days would be 140 points). Once 1000 points are reached, guests get a free stay. Guest details...
