1. What is the present value of a seven-year $100,000 annuity due if the annual opportunity cost is 7%? 2. I have $10,000 right now. I need $14,000 at the end of year 4. What interest rate must I receive to turn $10,000 into $14,000? If I invest $1,000 at the end of each year every year for the next seven years in an account paying 4% annual interest, how much will I receive at the end of 7 years
