Consider a hospital that has a demand curve given by P=180-4Q. Their total cost curve is given by TC=95+2Q. a) Please write down the expression for MR (marginal revenue) and MC (marginal cost) b)What will be the optimal P and Q? What will be their total revenue and their profits that result? c)Please shade in and indicate on the graph the areas that represent the total revenue and the total costs at these optimal P and Q. (Indicate them clearly)
