3. The current price of a stock is $54, and the annual risk-free rate is 2.5%. A call option with a strike price of $50 and with 75 days until expiration has a current value of $6.72. What is the value of a put option written on the stock with the same exercise price and expiration date as the call option? (Note: Use put call parity to determine price.)
