Draw a payoff diagram, and calculate the maximum loss, maximum gain, and breakeven for each of the following strategies.

Question 1: A call bull spread strategy: long the June 125 and short the June 130 calls.

Question 2: A put bear spread: long the June 130 put and short the June 125 put.

Question 3: Buy the stock at $125.94, buy the July 120 put for $13.65, and sell a call that has the same price, $13.65. But no such call exists! It turns out that I can create such a call if its exercise price were $136.165. [Hint: this is a collar.]
