Suppose a call option with a strike price of $$35$ costs $$4.$ Suppose a put option with a strike price of $$35$ also costs $$4.$ You decide to enter a strip $(\backslash /),$ which has a slope of negative $2$ prior to the kink point and positive $1$ after the kink point. What is the profit of the strategy if the stock price is $42$ at expiration?
