A call option with a current value of $10.20. A put option with a current value of $8.20. Both options written on the same stock and both with 1 year until expiration. The current price of the stock is $53.00 and the prevailing risk-free rate is 9.00%. What must be the striking price of either option? *** In your calculations, use simple discounting instead of continuous discounting. Also, do not enter the dollar sign and use two decimals (round off to 2 decimals).
