2. What is the present value of $7,000 due 8 periods hence, discounted at 11%?

3. What is the future value of 15 periodic payments of $7,000 each made at the end of each period and compounded at 10%

4. What is the present value of $7,000 to be received at the end of each of 20 periods, discounted at 5% compound interest?
