1. What is the present value of a seven-year $100,000 annuity if the annual opportunity cost is 4% ? 2. I have $9,000 right now. I need $14,000 at the end of year 4. What interest rate must I receive to turn $9,000 into $14,000 ? 3. If I invest $2,000 at the start of each year every year for the next four years in an account paying 4% annual interest, how much will I receive at the end of 4 years
