Suppose I secure a simple interest note for $4500.  The length of the note is 102 months and the interest is 6.2%.  How much will I owe the bank when the note comes due?

You would like to have $78,000 in 12 years. To accumulate this amount, you plan to deposit an equal sum in the bank each year that will earn 9% interest compounded annually. Your first payment will be made at the end of the year. a. How much must you deposit annually to accumulate this amount? b. If you decide to make a large lump-sum deposit today instead of the annual deposits, how large should the lump-sum deposit be? (Assume you can earn 9% on this deposit) c. At the end of year 5, you will receive $10,000 and deposit it in the bank in an effort to reach your goal of $78,000 at the end of year 12. In addition to the lump-sum deposit, how much must you invest in 12 equal annual deposits to reach your goal? (Again, assume you can earn 9% on this deposit)

A bank is offering a special deal. If you invest X now, the bank will give you 15,000 at time 7; 14,000 at time 8; 13,000 at time 9; and so on with the last payment being at time 14. Using an annual effective interest rate of 8%, determine X.

Suppose you deposit $1,181.00 into an account 5.00 years from today. Exactly 18.00 years from today the account is worth $1,800.00. What was the account's interest rate?
