Suppose a stock is currently selling at $42, and there are two call options available on this stock with the following characteristics. One call option with strike price of $40 is selling at $4, whereas another call option with strike price of $45 is selling at $2. You construct a bull spread, which means you purchase the call with the lower strike price and write the call with the higher strike price.

b. What is the break-even stock price?

c. What is the most you could lose in this strategy?

d. What is the most you could make in this strategy?

e. Construct a graph showing how net profit varies with stock price at expitation for this bull spread.
