4. You are willing to pay another party 10,000 today in exchange for 5 annual payments of 2500 each. What interest rate did you use to determine 10,000 was equivalent to the stream of payments?
a) The payments are made at the beginning of each year.
b) The payments are made at the end of each year.
5. The parents of three children, ages 1, 3, and 6, wish to set up a trust fund that will pay X to each child upon attainment of age 18, and Y to each child upon attainment of age 21. They will establish the trust fund with a single investment of Z. Which of the following is the correct equation of value for Z?
6. Briana deposits $100 into a bank account. Her account is credited interest at a nominal rate of 6% convertible semiannually. At the sametime, Pete deposits $100 into a separate account. Pete’s account is credited interest at a force of interest of δ . After 7.75 years, the value of both accounts are the same. Calculate δ .

7. You pay another party 10,000 today in exchange for them paying you 8% interest at the end of every year for 5 years and then return the 10,000 at the end of 5 years. You can reinvest the interest payments at 6%. How much will you have in total in 5 years?
8. You invest payments of 2000 per year at the beginning of each year for 8 years. The original payments earn 8% interest, but the interest received on the payments must be reinvested at 5%. How much will you have at the end of 8 years.
9. A store is running a promotion during which customers have two options for payment. Option one is to pay 90% of the purchase price two months after the date of sale. Option two is to deduct X% off the purchase price and pay cash on the date of sale. A customer wishes to determine X such that he is indifferent between the two options when valuing them using an effective annual interest rate of 8%. Set up an equation that the customer need to solve.
10. An annuity immediate has a first payment of 300 and increases by 100 each year until payments reach 800. There are 4 further payments of 800. Find the present value at 7%.
