Consider the following table of Put prices for an asset with S0 = 89 and no dividends:

Strike Premium

100 15

90 8

85 5

a) Using the above information ONLY, find the best no-arbitrage bounds on the Put premium with strike K = 95. You should specify both the lower P and upper bound P ?: P

b) Youre told that the premium for a Call with strike K = 90 is $10. Using this information, find the premium for a Call with strike K = 100 (hint: use put-call parity at K = 90 to find out e?rT ; then use put-call parity at K = 100).
