- 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_forwardMegan invested $21,000 in a savings account.

- Suppose that you borrow 20000 dollars from a bank, and that the bank charges 4 percent annual interest, compounded monthly, on the loan. You make monthly payments of 200 dollars at the end of each month. Write down a word equation that can be used to calculate the amount that is owed on the loan at the end of the month in terms of the amount owed at the start of the month. Writing the monthly balance (i.e. how much is owed) as yn , translate your word equation into mathematical terms. Simplify this equation. If we write Yn+1 = a yn + b, what are the values of a and b? a = 1.003 b = 8 What is the value of yo? Yo = 20000arrow_forwardShenseeastocking of $4,300 in account today.
