I have gone through quite a few exercises using Black-Scholes equation (or formula as you wish to call it). However, I am not quite understand the following question:
A stock is currently selling at $S_0= \$92$ and that the risk-free continuously compounded annual rate is $r=0.018$. Suppose that the exercise price is $K=\$98$ and the volatility of annual log-returns is $\sigma=0.2$.
If one quarter from now, the stock price is $\$95$, what is the price of the call?
Any hints would be greatly appreciated.
