Using excel, for each scenario graph the value of your portfolio as a function of the relevant stock price. For each of the four graphs, graph for stock prices between 100 and 160. Assume today is the last day for exercising your options. (Each graph should have at least 50 data points.)

- You own (are long) a call with an exercise price of 103 and a put at 120.

- You are short a call at 120, and long a put at 130.

- Short a call at 125, long a put at 153, and long one share of the stock.

- Long a call at 135, short a put at 115, short a share of stock.
