1. Consider a perfectly competitive market where demand is given by P=84.20-2.15Q and supply is given by P=12.78+1.20Q. Calculate the equilibrium price.
2. A medical device company has a monopoly on a certain class of cardiac implants. Demand for the implants is given by P=28000-5Q and marginal revenue is given by MR=28000-10Q. The total fixed costs for the implants division is 50000 and the marginal cost is given by MC=6000, so TC=50000+6000Q. Calculate the profit-maximizing quantity.
