Discussion- Assume Mike Inc.'s stock price changes at every month: Let's take a simple world: the stock price can either increase by 30% or falls by 20% every month. Its price now is $50. The interest rate is 6% per year (or equivalently, 6%/12 = 0.5% per month). Please answer following questions:

1. What is the value of a one-month call option with an exercise price of $50?
2. What is the option delta?
3. Show how the payoffs of this call option can be replicated by buying Mike's stock and borrowing.
