A put option with a strike price of $20 sells for $3.70. The option expires in four months, and the current stock price is $22.30. If the risk-free interest rate is 5.3 percent, what is the price of a call option with the same strike price? (Do not round intermediate calculations. Round your answer to 2 decimal places. Omit the "$" sign in your response.)
