The price of one share of JMN stock is 66.57. Options on this stock that expire in two months (1/6 of a year) are as follows:

Strike Price	Call	Put
65.00	4.65	3.05
67.50	3.43	4.33
70.00	2.47	5.87

Assuming the current continuously compounded risk-free rate is 6%:

a.) Draw the payoff and profit diagrams for a long 67.50 put option. Label as many of the important points along the graphs as you can.

b.) Suppose you construct a portfolio consisting of one long put with a strike price of 70.00 and one short put with a strike price of 65.00.

What would be the cost of establishing the portfolio?

If the price of one share at the end of two months is 67.15, what profit did the portfolio realize?
