A deposit account pays 12% per annum with continuous compounding, but interest is actually paid quarterly. How much interest will be paid each quarter on a $10,000 deposit?

A stock is currently selling for $64 per share. A call option with an exercise price of $70 sells for $4.75 and expires in four months. If the risk-free rate of interest is 2.4 percent per year, compounded continuously, what is the price of a put option with the same exercise price?
