Suppose that there are two possible states of the economy, A and B, in year T. A stocks price in year T will depend on the economic state as in the table below. A risk-free bond currently sells for $8 and it will pay $10 in year T in every state.

	state a	state b
stock	$150	$80
bond	$10	$10

In addition, we also see a year-T European call option on the stock above. The call has the strike price of $100 and currently sells for $20. What is the current stock price?
