Consider two "corresponding" options, consisting of a call and a put with the exact same parameter values. For this pair, the call premium is $7.1. If the current price of the underlying asset is $50 and the present value of the exercise price is $50, what is the premium of the put option, P? Write the answer with one decimal; e.g., 3.2. Do NOT use the $ symbol in your answer; just write a numerical value
