You purchase 100 options (you will need to calculate the price of the ?option) and go short the appropriate number of shares to hedge the position (for simplicity, assume that one option controls one share and that you must buy or sell whole shares of stock by rounding at 0.5). Assume that the stock price increases to $85 immediately so that no time has passed. Recalculate the option price using the Black-Scholes equation. Compute the total profit. (There is no need to consider interest on the short proceeds because no time has passed between valuations.)
