You are attempting to value a call option with an exercise price of $109 and one year to expiration. The underlying stock pays no dividends, its current price is $109, and you believe it has a 50% chance of increasing to $131 and a 50% chance of decreasing to $87. The risk-free rate of interest is 8%. Calculate the call options value using the two-state stock price model. (Do not round intermediate calculations. Round your final answer to 2 decimal places.)
