1. You operate in an environment in which you can earn 5% compounded semi-annually after taxes and no more. If someone promised you $1,638.62 at the end of 10 years, what would you pay today for that promise, assuming you knew you could trust the promisor?

2. Assume instead you had cash of $1,000 and that you were offered $1,344.89 payable at the end of year 6 to lend it. a. Would you agree to the deal? b. What would you agree to if you had other investment opportunities that paid 10% compounded semi-annually?
