Mixing options and securities can often create interesting payoffs. For each of the following combinations, show what the payoff would be when the option expires if (i) the stock price is below the exercise price and (ii) the stock price is above the exercise price. Assume that each option has the same exercise price and expiration date.

Consider options with an exercise price of $100. Call the stock price at the expiration date S. Note that your answer may be a number or may be a relationship to S, such as S+10.
