You sell short 200 shares of Wells Fargo &Co that are currently selling at $60 per share. You post the 0.5 margin required on the short sale. If your broker requires a 0.4 maintenance margin, at what stock price will you get a margin call? (You earn no interest on the funds in your margin account, and the firm does not pay any dividends.)

Answer is 64.29. Please show steps.
