Financial Planner One part of the job of a financial planner is to help people invest their money appropriately. If a customer knows he or she will need a certain amount of money in 10 or 20 years the financial planner can help the customer plan how much needs to be invested today and and at what rate in order to have that amount When a principal P earns an annual interest rate r compounded yearly the amount A after t years is
What interest rate would be necessary to obtain $6500 in 6 years if $5000 is the amount of the original investment and the interest is compounded yearly? (Express the interest rate as a percent rounded to the nearest tenth.)

- The annual percentage yield (APY) of an investmentaccount is a representation ofthe actual interest rateearned on a compounding account. It is based on acompounding period of one year. Show that the APYof an account that compounds monthly can be foundwith the formula APY=(1+r12)121.arrow_forwardAn Amortization Table Suppose you borrow P dollars at a monthly interest rate of r as a decimal and wish to pay off the loan in t months. Then your monthly payment can be calculated using M=Pr(1+r)t(1+r)t1 dollars. Remember that for monthly compounding, you get the monthly rate by dividing the APR by 12. Suppose you borrow 3500 at a 9 APR meaning that you use r = 0.09/12 in the preceding formula and pay it back in 2 years. a. What is your monthly payment? b. Lets look ahead to the time when the loan is paid off. i. What is the total amount you paid to the bank? ii. How much of that was interest? c. The amount B that you still owe the bank after making k monthly payments can be calculated using the variables r, P, and t. The relationship is given by B=P((1+r)t(1+r)k(1+r)t1) dollars. i. How much do you still owe the bank after 1 year of payments? ii. An amortization table is a table that shows how much you still owe the bank after each payment. Make an amortization table for this loan.arrow_forwardAn Uncertain Investment Suppose you invested 1300 in the stock market two years ago. During the first year the value of the stock increased by 12%. During the second year, the value of the stock decreased by 12%. How much money is your investment worth at the end of the two-year period? Did you earn money or lose money? Note: The answer to the first question is not 1300arrow_forward
- Future Value In certain savings scenarios, the value F of an investment after t years, the future value, is given by F=P1+rt. Here r is the yearly interest rate as a decimal, P is the amount of the original investment and t is the term of the investment. If we invest 1000 at an interest rate of 0.06 per year as a decimal, and if the term of the investment is 5 years, what is the future value?continuedarrow_forwardCompound Interest Use the formula A=P1+rnnt to calculate the balance A of an investment when P=$3000, r=6 and t=10years, and compounding is done (a) by the day, (b) by the hour, (c) by the minute, and (d) by the second. Does increasing the number of compoundings per year result in unlimited growth of the balance? Explain.arrow_forward
