Could you show me how to figure out the problem? Thanks

A European call option written on one share of Medident Corp. has the following parameter values: S = $220. X = $200, 1 = 5% p.a., sigma = 40% p.a., T = 3 months. Find the call option's premium, rounded to 2 decimals (e.g. 3.24). Do NOT include the S sign in your answer, write only the numerical value. NOTE: Use the continuous time version of the Black-Scholes equation (i.e., do NOT use the book's version)
