You are attempting to value a call option with an exercise price of $150 and one year to expiration. The underlying stock pays no dividends. Its current price is $100. The stock price either increases by a factor of 1.5, or decreases by a factor of 0.5, every six months. The risk-free rate of interest is 2% per year (or 1% per six-month period). What is the value of this call option using the two-period binomial option pricing model? (Do not round intermediate calculations. Round your answer to 3 decimal places.)
