Suppose that the risk free rate is 5% per year. We wish to value a 2-year American call option with a strike price of $110. The current stock price is $100. Each year, the stock price either increases 10%, or decreases by 5%

Here are the steps for you to solve the problem

Construct a two-period binomial tree for the value of the stock. (5 points)

Calculate the value of the American call option. (10 points)

Write down the put-call parity relationship for this option. (2 points)

What will be the value of the European put option with an exercise price of 110? (3 points)
