Consider a one-period binomial model for a long straddle (which results in a payoff of St-K). A stock is currently priced at $100 and goes up by 10% or down by 7% in each time period. Assume an interest rate of 5% in each time period. If you purchase a straddle with a strike price of $110 and price it using a 2-period binomial model, what is the appropriate price?
